Answer: 60,000
Explanation:
Since we are given the information that the beginning work in process are 40,000 units and units started this period are 20,000 units, then the total units to account for will be the addition of the beginning work in process and the units started this period. This will be:
= 40000 + 20000
= 60000
Therefore, the total units to account for is 60000.
Private solutions to correct for externalities Consider the following scenario: Suppose that a chicken farm uses a nearby stream to dispose of the wastes released by its chickens. These wastes flow downstream into a lake that has become thick with algae and polluted by the minerals in the waste matter. The local office of a nonprofit environmental organization collects enough donations to fund a campaign to stop the farm's pollution. Which of the following types of private solutions to the externality of pollution has occurred in this case?A. Integration of different types of businessesB. ContractsC. Moral codes and social sanctionsD. Charities
Answer:
D
Explanation:
The activities of the chicken firm constitutes a negative externality to the environment
A good has negative externality if the costs to third parties not involved in production is greater than the benefits. an example of an activity that generates negative externality is pollution. Pollution can be generated at little or no cost, so they are usually overproduced. Government can discourage the production of activities that generate negative externality by taxation. Taxation increases the cost of production and therefore discourages overproduction. Tax levied on externality is known as Pigouvian tax.
Government can regulate the amount of externality produced by placing an upper limit on the amount of negative externality permissible
Coase theorem has been proposed as a solution to externality. According to this theory, when there are conflicting property rights, bargaining between parties involved can lead to an efficient outcome only if the bargaining cost is low
Another solution to negative externality is through the activities of charities. Charities can raise donations to limit or regulate the activities of firms that constitutes a negative externality. This is the solution employed here.
What is the present value of a perpetuity that offers to pay $100 next year and every year after the payment grows at 4.3%. Investments with similar risk are offering an 8% annual return.
Answer:
PV= $2,702.70
Explanation:
Giving the following information:
Cash flow= $100
Growth rate (g)= 4.3%
Discount rate (i)= 8%
To calculate the present value of the perpetuity, we need to use the following formula:
PV= Cf / (i - g)
PV= 100 / (0.08 - 0.043)
PV= 100 / 0.037
PV= $2,702.70
John believes his sales team's performance is due to outside forces, like economic and market factors. Which of the following best describes is John's locus of control?
a. External
b. Market driven
c. Internal
d. Based on labor trends.
Answer:
a. External
Explanation:
There are only two types of locus of control and these are internal and external. In this scenario, John's locus of control would be external. This is because John is connecting various external forces that he cannot control, to the performance of the sales team. This indicates an external locus of control. If John where to instead attribute something such as hard work and training to his sales team's perfomance, then that would be considered an internal locus of control.

A bond has a yield to maturity (YTM) of 9.00%. If the YTM decreases to 8.90%, then the price of the bond will_____.
Answer:
increase
Explanation:
The expected average rate of return for a proposed investment of $4,250,000 in a fixed asset, using straight-line depreciation, with a useful life of 20 years, no residual value, and an expected total net income of $8,500,000 over the 20 years is:_________ (round to two decimal points).
a. 10.00%
b. 20.00%
c. 40.00%
d. 1.00%
Answer:
A
Explanation:
Average rate of return is a capital budgeting method. It is used to determine if a firm should invest in a project or should not invest in a project
average rate of return = average net income / average cost of investment
average net income = (total net income - depreciation) / useful life
(8,500,000 - $4,250,000) / 20 = 212,500
Average cost of investment =( beginning book value of the investment - ending book value of the investment) / 2
($4,250,000 - 0) / 2 = 2,125,000
ARR = 212,500 / 2125,000 = 0.1 = 10%
The acid-test ratio differs from the current ratio in that: _______
a) The acid-test ratio is a measure of liquidity but the current ratio is not.
b) Liabilities are divided by current assets
c) The acid-test ratio measures profitability and the current ratio does not.
d) Prepaid expensand inventory are excluded from the calculation of the acid-test ratio.
e) The acid-test ratio excludes short-term investments from the calculation.
Answer:
d) Prepaid expensand inventory are excluded from the calculation of the acid-test ratio.
Explanation:
The acid-test can be regarded quick ratio, this ratio makes the comparison between most short-term assets of a company and most short-term liabilities of the company in order to ascertain if there is enough cash for the company to pay immediate liabilities in the company. These immediate liabilities could be short-term debt. There is usually disregards of current assets by acid-test ratio which it's liquidation is difficult example is inventory.
Current ratio can be regarded as ratio that compares current assets of a company and the current liabilities. It can be gotten by finding ratio of current assets of the company and current liabilities. liquidity of a company can be measured using current ratio by potential creditors.
It should be noted that The acid-test ratio differs from the current ratio in that Prepaid expensand inventory are excluded from the calculation of the acid-test ratio.
Risk assessment is an evaluation of the PPS supported by a number of analysis methodologies, including :__________.
Answer:
Threat analysis Consequence analysis Event and Fault tree analyses Vulnerability analysisExplanation:
Threat Analysis
Involves the identification of areas of the system in question that are vulnerable to risk and then identifying what those risks are.
Consequence Analysis
With consequence analysis, the possible effects of the risks identified will be analyzed to see how much damage they can cause.
Event and Fault tree analyses
Here a tree is used to show all of the possible effects of a risky activity failing. It is used to find out the cause of the worst case scenario.
Vulnerability analysis
As the term implies, vulnerability analysis is done to see which parts of a system are at risk and how vulnerable they are to this risk and then ranking these vulnerabilities so that they can be prioritized.
The cost object of the plantwide overhead rate method is: Multiple Choice The production departments of the company. The unit of product. The production activities of the company.
Answer: The unit of product.
Explanation:
The units produced of the goods being produced will be the appropriate cost object because it will apportion the overhead cost to the plant based on how much goods were produced by the plant itself because this would determine how much overhead the plant used.
Manufacturing overheads only occur because goods are being produced which is why the best cost object would be those same goods being produced.
Payne Company provided the following information relevant to its inventory sales and purchases for December 2013 and the first quarter of 2014:
Dec. 2013 Jan. 2014 Feb. 2014 Mar. 2014
(Actual) (Budgeted) (Budgeted) (Budgeted)
Cost of goods sold $80,000 $140,000 $180,000 $120,000
Desired ending inventory levels are 25% of the following month's projected cost of goods sold. The company purchases all inventory on account. January Year 2 budgeted purchases are $180,000. The normal schedule for inventory payments is 60% payment in month of purchase and 40% payment in month following purchase.
Budgeted cash payments for inventory in February 2014 would be: __________
Answer:
$171,000
Explanation:
Purchases in February = ($120,000 * 25%) + ($180,000 -$180,000*25%)
Purchases in February = $30,000 + $135,000
Purchases in February = $165,000
Payment in February = ($180,000 * 40%) + ($165,000 * 60%)
Payment in February = $72,000 + $99,000
Payment in February = $171,000
So, the bdgeted cash payments for inventory in February 2014 will be $171,000.

Sweet Treats common stock is currently priced at $17.15 a share. The company just paid $1.22 per share as its annual dividend. The dividends have been increasing by 2.4 percent annually and are expected to continue doing the same. What is this firm's cost of equity
Answer:
9.68 percent
Explanation:
Calculation to determine the firm's cost of equity
Using this formula
Cost of equity=[(Annual dividend×Increase in dividends×/Current price of common stock]+Dividends
Let plug in the formula
Cost of equity=[($1.22 × 1.024)/$17.15] + 0.024
Cost of equity=($1.24928/$17.15)+0.024
Cost of equity=0.0728+0.024
Cost of equity=0.0968*100
Cost of equity=9.68 percent
Therefore the firm's cost of equity is 9.68 percent
Which of these is more likely to be true?
A. An adaptor is likely to consider radical innovations
B. An innovator is likely to consider incremental innovations
C. Large companies often find it easier to adopt radical innovations.
D. Innovators will often push for radical innovations.
Answer: D. Innovators will often push for radical innovations.
Explanation:
A radical innovation is one that when made, changes up the way things were being done in the industry that it appears in. For instance, when the first digital camera was made, it changed photography forever.
This is what innovators want. They want to come up with a product that would change the way things are being done and enable them to take over the market.

A monopolist, unlike a competitive firm, has some market power. It can raise its price, within limits, without the quantity demanded falling to zero. The main way it retains its market power is through barriers to entry—that is, other companies cannot enter the market to create competition in that particular industry.Complete the following table by indicating which barrier to entry appropriately explains why a monopoly exists in each scenario.ScenarioBarriers to EntryExclusive Ownership of a Key ResourceGovernment-Created MonopoliesEconomies of ScaleThe Aluminum Company of America (Alcoa) formerly controlled all U.S. sources of bauxite, a key component in the production of aluminum. Given that Alcoa did not sell bauxite to any other companies, Alcoa was a monopolist in the U.S. aluminum industry from the late-nineteenth century until the 1940s. Patents are granted to inventors of a product or process for a certain number of years. The reason for this is to encourage innovation in the economy. Without the existence of patents, it is argued that research and development for improved pharmaceutical products is unlikely to take place, since there's nothing preventing another firm from stealing the idea, copying the product, and producing it without incurring the development costs. In the natural gas industry, low average total costs are obtained only through large-scale production. In other words, the initial cost of setting up all the necessary pipes and hoses makes it risky and, most likely, unprofitable for competitors to enter the market.
Answer:
Monopolist's Market Power and Barriers to Entry
Scenario 1
The Aluminum Company of America (Alcoa) formerly controlled all U.S. sources of bauxite, a key component in the production of aluminum. Given that Alcoa did not sell bauxite to any other companies, Alcoa was a monopolist in the U.S. aluminum industry from the late-nineteenth century until the 1940s.
Barrier to Entry:
Exclusive Ownership of a Key Resource
Scenario 2
Patents are granted to inventors of a product or process for a certain number of years. The reason for this is to encourage innovation in the economy. Without the existence of patents, it is argued that research and development for improved pharmaceutical products is unlikely to take place, since there's nothing preventing another firm from stealing the idea, copying the product, and producing it without incurring the development costs.
Barrier to Entry:
Government-Created Monopolies
Scenario 3:
In the natural gas industry, low average total costs are obtained only through large-scale production. In other words, the initial cost of setting up all the necessary pipes and hoses makes it risky and, most likely, unprofitable for competitors to enter the market.
Barrier to Entry:
Economies of Scale
Explanation:
Exclusive Ownership of a Key Resource: It has been argued that monopolies do not arise from exclusive ownership of a key resource. However, having exclusive ownership grants an entity a kind of natural monopoly.
Government-Created Monopolies: Governments create monopolies by protecting intellectual property and issuing patents and copyrights, which give the holders exclusive rights to produce some products or render some services for a period of time. The purpose is to encourage innovation and industrialization.
Economies of Scale: When a company is able to produce goods in large quantity, this reduces the average cost per unit, increases efficiency, and economies of scale are achieved because the costs of production are spread over larger units.
Copy equipment was acquired at the beginning of the year at a cost of $56,000 that has an estimated residual value of $8,000 and an estimated useful life of 5 years. It is estimated that the machine has an estimated 1,000,000 copies. This year 240,000 copies were made. Determine the (a) depreciable cost, (b) depreciation rate, and (c) the units-of-production depreciation for the year.
Answer:
Results are below.
Explanation:
The depreciable cost is the result of deducting from the purchase price the salvage value:
Depreciable cost= 56,000 - 8,000
Depreciable cost= $48,000
The depreciable rate is the depreciation that the asset suffers in one year express as a percentage:
Depreciation rate= 1/5 = 0.2 or 20% per year
Finally, the units of production depreciation for the first year:
Annual depreciation= [(original cost - salvage value)/useful life of production in copies]*number of copies
Annual depreciation= (48,000/1,000,000)*240,000
Annual depreciation= 0.048*240,000
Annual depreciation= $11,520
On its balance sheet, Walgreen Co. reports treasury stock at cost of $4,114 million. The company has a total of 1,100,000,000 shares issued and 950,000,000 shares outstanding. What average price did Walgreen pay for treasury shares?
a. $3.15.b. $3.29.c. $3.03.d. $38.1.
Answer:
$2.74
Explanation:
Calculation to determine What average price did Walgreen pay for treasury shares
Price per share =total treasury shares at cost/treasury shares.
Price per share=$4,114 million / (1,100,000,000 – 950,000,000)
Price per share=$4,114 million/
= $2.74 per share.
Consider a stock priced at $30 with a standard deviation of 0.3. The risk-free rate is 0.05. There are put and call options available at exercise prices of 30 and a time to expiration of six months. The calls are priced at $2.89 and the puts cost $2.15. There are no dividends on the stock and the options are European. Assume that all transactions consist of 100 shares or one contract (100 options). Suppose the investor constructed a covered call. At expiration the stock price is $27. What is the investor's profit
Answer:
-$11
Explanation:
Covered Call involves Buy stocks and Sell call options
Earning $2.89 by selling call. So, at stock price of $27, the payoff from options is $2.89 per option
Options Profits = $2.89 * 100
Options Profits = $289
Profit of stock = ($27 - $30) * 100
Profit of stock = -$300
Investor Net Profit = Profit of stock + Options Profits
Investor Net Profit = -$300 + $289
Investor Net Profit = -$11

g Suppose a commercial bank has checkable deposits of $80,000 and the legal reserve ratio is 20 percent. If the bank's required and excess reserves are equal, then its actual reserves
Answer:
$32,000
Explanation:
The computation is shown below;
Required reserves = checkable deposits × legal reserve ratio
= $80,000 × 20%
= $16,000
Now the actual reserves is
= $16,000 + $16,000
= $32,000
Also excess reserve is equivalent to the required reserves
Hence, the actual reserves is $32,000

Jammer Company uses a weighted average perpetual inventory system and reports the following:
August 2 Purchase 24 units at $18.50 per unit. August 18 Purchase 26 units at $20.00 per unit. August 29 Sale 48 units. August 31 Purchase 29 units at $21.50 per unit.
What is the per-unit value of ending inventory on August 31? (Round your per unit answers to 2 decimal places.)
Answer: $21.36
Explanation:
Weighted average inventory system works by taking the average of the inventory prices on the different days.
Price on August 29 which is date of sale:
= {(Units purchased on August 2 * Unit cost on August 2) + ( Units purchased on August 18 * Unit cost on August 18)] / (Units purchased on August 2 + Units purchased on August 18)
= [ ( 24 * 18.50) + (26 * 20) ] / (24 + 26)
= $19.28 per unit
48 units were sold so the number of units left are:
= 24 + 26 - 48
= 2 units
Price on August 31
= [ (Units remaining on August 29 * Unit cost on August 29) + ( Units purchased on August 31 * Unit cost on August 31)] / (Units remaining on August 29 + Units purchased on August 31)
= [ (2 * 19.28) + (29 * 21.50) ] / ( 2 + 29)
= $21.36
Agreement and disagreement among economists
Suppose that Raphael, an economist from an AM talk radio program, and Susan, an economist from a nonprofit organization on the West Coast, are arguing over saving incentives. The following dialogue shows an excerpt from their debate:
Yvette: I think it's safe to say that, in general, the savings rate of households in today's economy is much lower than it really needs to be to sustain the improvement of living standards.
Sean: I think a switch from the income tax to a consumption tax would bring growth in living standards.
Yvette: You really think households would change their saving behavior enough in response to this to make a difference? Because I don't.
1. The disagreement between these economists is most likely due to (differences in values, differences in perception versus reality, differences in scientific judgments) .
2. Despite their differences, with which proposition are two economists chosen at random most likely to agree?
A. Lawyers make up an excessive percentage of elected officials.
B. Minimum wage laws do more to harm low-skilled workers than help them.
C. Tariffs and import quotas generally reduce economic welfare.
Answer:
Differences in values C. Tariffs and import quotas generally reduce economic welfare.Explanation:
Yvette and Sean most likely have a difference in values because they believe that one thing is better for the economy than the other. This means that when it comes down to the economy, they value a certain approach over other approaches.
Economist don't usually find common ground on many things but there are some things where they have a general consensus and one of them is that tariffs and import quotas are bad for the economy. They believe that people stand more to gain from free trade than restricted trade.
Assume that the U.S. borrowing rate is 8% while the German is 10%. If Euros are borrowed by a U.S. firm for one year, they would have to _____ against the dollar by_____ to have the same effective financing rate as borrowing dollars.

U.S. has a borrowing rate of 8% and German has borrowing rate of 10%. If U.S. dollars are borrowed from firm then Euros will depreciate to match with the dollar borrowing.
[1 + 8% ] / [ 1 + 10%] - 1 = - 1.1818
Crane Corporation's computation of cost of goods sold is:
Beginning inventory $34800
Add: Cost of goods purchased 470000
Cost of goods available for sale 504800
Less: Ending inventory 72000
Cost of goods sold $432800
The average days to sell inventory for Fry are:________
Answer:
16.64 days
Explanation:
Given the above information, we will calculate the average days to sell inventories with the formula below;
Average days to sell inventories = [Ending inventory / Cost of goods sold] × 100
Ending inventory = $72,000
Cost of goods sold = $432,800
Then, Average days to sell inventories
= [$72,000 / $432,800] × 100
= 16.64 days
Therefore, the average days to sell inventory for Fry are 16.64 days

The spread of ATMs and the increased use of debit cards _______ money. Everything else remaining the same, the nominal interest rate _______.
Answer:
increase the demand for; falls
Explanation:
ATMs means automated teller machine. They increase the ease through which a bank account holder can assess her funds. ATMs can be used to :
withdraw funds check account balancetransfer moneyWith the proliferation of ATMs and the increased use of debit cards, there has been an increase in the demand for money. This has led to a fall in nominal interest rate
The demand for money (the decision to hold money) is inversely related to interest rate. If the demand for money increases, it means that less bonds are been held. As a result, there would be a fall in the interest rates.

Answer: C) automatically considered because the after-tax cost of debt is included within the WACC formula.

When calculating the Weighted Average Cost of Capital (WACC) for a levered firm, the interest tax shield is included because the cost of debt used is adjusted for tax as shown below:
= (Weight of debt * Cost of debt( 1 - tax rate) ) + (Weight of equity * cost of equity)
As shown above, the interest tax shield is already implicit in the formula so there is no need to adjust the levered firm for an interest tax shield as this would lead to double-counting.
