Answers

Answer 1

Answer:

Amount needed to have in account = 99272

Explanation:

Below are the calculations:

Annual income after retirement, annuity = $8000

The time period or the retirement life = 30 years

The Interest rate earned by account = 7%

The amount in the account at the time of retirement = Annuity (P/A, r, n)

The amount in the account at the time of retirement = 8000 (P/A, 7%, 30)

The amount in the account at the time of retirement = 8000 x 12.409

The amount in the account at the time of retirement = 99272

Compare a market operating at a quantity lower than equilibrium (ie. a price floor) with the same market operating at the equilibrium quantity. Which of the following statements are true?

a. A price floor will increase the producer and total surplus.
b. It is unclear if the consumer surplus is greater or less at the market operating below equilibrium.
c. A market operating below equilibrium will transfer some producer surplus to consumers
d. A market operating below equilibrium will transfer some consumer surplus to producers.

Answers

Answer:

D

Explanation:

A price floor is when the government or an agency of the government sets the minimum price of a product. A price floor is binding if it is set above equilibrium price.

A price floor increases producer surplus and reduces consumer surplus

Consumer surplus is the difference between the willingness to pay of a consumer and the price of the good.

Consumer surplus = willingness to pay – price of the good

Producer surplus is the difference between the price of a good and the least price the seller is willing to sell the product

Producer surplus = price – least price the seller is willing to accept

The dead weight loss of tax can be determined by calculating the reduction in total surplus as a result of the tax

Computech Corporation is expanding rapidly and currently needs to retain all of its earnings; hence, it does not pay dividends. However, investors expect Computech to begin paying dividends, beginning with a dividend of $0.50 coming 3 years from today. The dividend should grow rapidly - at a rate of 49% per year - during Years 4 and 5; but after Year 5, growth should be a constant 9% per year. If the required return on Computech is 16%, what is the value of the stock today? Round your answer to the nearest cent. Do not round your intermediate calculations.

Answers

Answer: $8.81

Explanation:

To solve this, add the present values of the dividends from years 3, 4 and 5 and then add the present value of the terminal value of the stock at year 5.

Year 3 dividend = $0.50

Year 4 dividend = 0.50 * (1 + 49%) = $0.745

Year 5 dividend = 0.745 * 1.49 = $1.11005

= Dividend in year 3 / (1 + required rate of return)³ + Dividend in year 4 / (1 + required rate of return)⁴ + Dividend in year 5 / (1 + required rate of return)⁵ +   (Dividend in year 5 * (1 + growth rate) / ( required rate of return - growth rate ) ) / (1 + required rate of return)⁵

= 0.5 / 1.16³ + 0.745/1.16⁴ + 1.11005/1.16⁵ + ( 1.11005 / (16% - 9%)) / 1.16⁵

= $8.81

If the required return on Compu tech is 16%, the value of stock today is $8.81. To answer this, sum the present values of the dividends from years 3, 4, and 5, followed by the present value of the stock's terminal value in year 5.

The current value of a future sum of money or stream of cash flows at a predetermined rate of return is known as its present value (PV). The present value of future cash flows is reduced by the discount rate, and the higher the discount rate, the lower the present value of future cash flows.

Given,

Year 3 dividend = $0.50

Year 4 dividend = 0.50 * (1 + 49%) = $0.745

Year 5 dividend = 0.745 * 1.49 = $1.11005

Dividend in year 3 / (1 + required rate of return)³ + Dividend in year 4 / (1 + required rate of return)⁴ + Dividend in year 5 / (1 + required rate of return)⁵ +   (Dividend in year 5 * (1 + growth rate) / ( required rate of return - growth rate ) ) / (1 + required rate of return)⁵

= 0.5 / 1.16³ + 0.745/1.16⁴ + 1.11005/1.16⁵ + ( 1.11005 / (16% - 9%)) / 1.16⁵

= $8.81

A company is planning to purchase a machine that will cost $57,000 with a six-year life and no salvage value. The company expects to sell the machine's output of 3,000 units evenly throughout each year. A projected income statement for each year of the asset's life appears below. What is the payback period for this machine?
Sales $138,000
Costs:
Manufacturing $68,000
Depreciation on machine 9,500
Selling and administrative expenses 46,000 (123,500)
Income before taxes $14,500
Income tax (35%) 5,075
Net income $9,425
a. 6.00 years.
b. 1.99 year.
c. 6.05 years.
d. 12.10 years.
e. 3.01 years.

Answers

Answer:

e. 3.01 years

Explanation:

Cost of Asset = $57,000  

Net annual cash Inflow = Net Income after Tax + Depreciation

Net annual cash Inflow = $9,425 + $9,500

Net annual cash Inflow = $18,925

Payback Period = Cost of Asset (Investment) / Net annual cash Inflow

Payback Period = $57,000 / $18,925

Payback Period = 3.01188904

Payback Period = 3.01 years

In the Shaping Department of Jenkins Company the unit materials cost is $3.00 and the unit conversion cost is $1.80. The department transferred out 8,000 units and had 2,000 units in ending work in process 20% complete. If all materials are added at the beginning of the process, the total cost to be assigned to the ending work in process is?

Answers

Answer:

$6,720

Explanation:

Calculation to determine what the total cost to be assigned to the ending work in process is

First step

Materials cost=2000 units * 100%

Materials cost=2,000

Conversion costs=2000 units *20%

Conversion costs= 400

Now let determine the ending work in process

Ending work in process=(2000 units *$3.00 per unit)+(400 units *$1.80 per unit)

Ending work in process= $6,000+$720

Ending work in process=$6,720

Therefore the total cost to be assigned to the ending work in process is $6,720

Interest earnings of 4 percent with a $450 minimum balance; average monthly balance, $600; monthly service charge of $20 for falling below the minimum balance, which occurs five times a year (no interest earned in these months). (Do not round intermediate calculations. Round your answer to 2 decimal places. Input the amount as a positive value.)

Answers

Answer:

$86

Explanation:

Missing word "What could be the net annual cost"

Monthly fee = $20

Interest rate = 4% = 0.04

Average monthly balance = $600

Net annual cost = $20*5 - 0.04*$600*7/12

Net annual cost = $100 - $14

Net annual cost = $86

So, the net annual cost of this account is $86.

Green Melon Electronics Company's management plans to finance its operations with bank loans that will be repaid as soon as cash is available. The company's management expects that it will take 60 days to manufacture and sell its products and 50 days to receive payment from its customers. Green Melon's CFO has told the rest of the management team that they should expect the length of the bank loans to be approximately 110 days.

Which of the following responses to the CFO's statement is most accurate?

a. The CFO is not taking into account the amount of time the company has to pay its suppliers. Generally, there is a certain length of time between the purchase of materials and labor and the payment of cash for them. The CFO can reduce the estimated length of the bank loan by this amount of time.
b. The CFO's approximation of the length of the bank loans should be accurate, because it will take 110 days for the company to manufacture, sell, and collect cash for its goods. All these things must occur for the company to be able to repay its loans from the bank.

Setting and implementing a credit policy is important for three main reasons:
1. It has a major effect on sales, it influences the amount of funds tied up in receivables, and it affects bad debt losses.
2. It has a minor effect on sales, it influences the amount of funds tied up in receivables, and it affects bad debt losses.

D2 = new demand

D1 = initial demand

P2 = new price

P1 = initial price.

Answers

Answer:

If inflation were 5%, the value of the call in 50 years would be $ 57.33; while if inflation were 10% the value of the call would be $ 586.95.

Explanation:

Given that a telephone call to London that currently would cost $ 5, to determine, if the real price of telephone calls does not change in the future, how much will it cost you to make a call to London in 50 years if the inflation rate is 5% and if inflation is 10%, the following calculations must be made:

5 x 1.05 ^ 50 = X

5 x 11.4674 = X

57.33 = X

5 x 1.1 ^ 50 = X

5 x 117.39 = X

586.95 = X

Therefore, if inflation were 5%, the value of the call in 50 years would be $ 57.33; while if inflation were 10% the value of the call would be $ 586.95.
