Answer: At least 1% of the purchase price
Explanation:
The 1% rule is a popular practice that estimates that 1% of a house´s purchase price should be expected to be required for maintenance every year. This is the case for a house that is less than five years old. Houses between 5 and 25 years old could range between a 1 and 4% annual maintenance budget, depending also on its location, the market, its size, and the impact of the weather.
The Bathtub Division of Kirk Plumbing Corporation has recently approached the Faucet Division with a proposal. The Bathtub Division would like to make a special "ivory" tub with gold-plated fixtures for the company's 50-year anniversary. It would make only 5,000 of these units. It would like the Faucet Division to make the fixtures and provide them to the Bathtub Division at a transfer price of $160. If sold externally, the estimated variable cost per unit would be $140. However, by selling internally, the Faucet Division would save $6 per unit on variable selling expenses. The Faucet Division is currently operating at full capacity. Its standard unit sells for $43 per unit and has variable costs of $25.
Required:
Compute the minimum transfer price that the Faucet Division should be willing to accept, and discuss whether it should accept this offer.
Answer:
Minimum transfer price = $152
Explanation:
The minimum transfer price can be calculated by Adding variable cost and the contribution margin lost
Minimum transfer price = Variable cost + Contribution margin lost
Minimum transfer price = $134 + $18
Minimum transfer price = $152
Working
Variable cost = $140 -$6(saving) = $134
Contribution margin lost = Selling price - variable cost per unit
Contribution margin lost = $43 - $25
Contribution margin lost = $18
Decision: The offer should be accepted because the minimum transfer price of $152 is less than $160
The minimum desired rate of return for net present value analysis is 12%. The present value of $1 at compound interest of 12% for 1, 2, 3, and 4 years is 0.893, 0.797, 0.712, and 0.636, respectively. Determine the net present value. $
Answer: $18,848
Explanation:
The Net Present Value of a project is the difference between the present values of the cash outflows and inflows.
Present Values of the Cash flows;
Year 1
= 150,000 * 0.893
= $133,950
Year 2
= 130,000 * 0.797
= $103,610
Year 3
=104,000 * 0.712
= $74,048
Year 4
= 90,000 * 0.636
= $57,240
Net Present Value = Cash inflows - Outflow
= 133,950 +103,610 + 74,048 + 57,240 - 350,000
= $18,848

3. There a number of market entry strategies that businesses use in entering into markets outside their countries. a) Distinguish between the use of Franchising and Joint Venture as modes of entry into other countries by global businesses. b) What are the respective advantages and disadvantages of both strategies?
Answer:
a) Distinguish between the use of Franchising and Joint Venture as modes of entry into other countries by global businesses.
Franchising consists in the licensing of aspects of production and intellectual property to a another party: the franchise.
A Joint Venture is a business union between two or more parties, in which they split profit as well as costs and responsabilities.
b) What are the respective advantages and disadvantages of both strategies?
Franchising can be a quicker way to expand into foreign markets. The flexibility of the method, and the lower capital requirements are the reason why. This can be seen in the success that American fast-food brands have had using this method to expand in global markets.
A Joint-Venture can be more difficult to use for market expansion, however, it can be more profitable, because the profit will not be split among as many parties as in franchising, and more importantly, the firm maintains a higher control of the operation.
Upton Co. is growing quickly. Dividends are expected to grow at 20 percent for the next three years, with the growth rate falling off to a constant 8 percent thereafter. If the required return is 11 percent and the company just paid a dividend of $1.45, what is the current share price
Answer:
$71.03
Explanation:
To find the current share price we need to find the value of future dividends first and then discount it by the given rate of return
DATA
Growth rate = g = 20%
Time period = 3 years
Required return = 11%
Current dividend = Do = $1.45
Share price =?
Solution
Future dividend = Current dividend ( 1 + growth rate)
D1 = (1.45 x 1.20) = $1.74
D2 = (1.74 x 1.20) = $2.088
D3 = (2.088 x 1.20) = $2.5056
Value after year 3 = (D3 x Growth rate) / (Required return-Growth rate)
Value after year 3 = (2.5056*1.08) / (0.11-0.08)
Value after year 3 =$90.2
current share price = Future dividends x Present value of discounting factor
current share price = (1.74/1.11)+($2.088/1.11^2)+(2.5056/1.11^3)+($90.2/1.11^3)
current share price = 1.56 + 1.69 + 1.83 + 65.95
current share price =$71.03
Cullumber Industries incurs unit costs of $7 ($5 variable and $2 fixed) in making an assembly part for its finished product. A supplier offers to make 14,700 of the assembly part at $6 per unit. If the offer is accepted, Cullumber will save all variable costs but no fixed costs. Prepare an analysis showing the total cost saving, if any, Cullumber will realize by buying the part. (Enter negative amounts using either a negative sign preceding the number e.g. -45 or parentheses e.g. (45).)
Answer and Explanation:
The preparation of the analysis that depicts the total cost saving is presented below:
Particulars Make Buy Net Income or decrease
Variable
Manufacturing Cost $73,500 - $73,500
(14,700 × $5)
Fixed
Manufacturing cost $29,400 $29,400 -
(14,700 × $2)
Purchase price
(14,700 × $6) - $88,200 ($88,200)
Total annual cost $102,900 $117,600 ($14,700)
Based on the total annual cost the company should make the product as it saves the cost by $14,700
A project has estimated annual net cash flows of $56,600. It is estimated to cost $339,600.
Required:
Determine the cash payback period.
Answer:
It will take exactly 6 full years to cover for the initial investment.
Explanation:
Giving the following information:
Cash flow= $56,600
Initial investment= 339,600
The payback period is the time required for the cash flow to cover the initial investment:
Year 1= 56,600 - 339,600= -283,000
Year 2= 56,600 - 283,000= -226,400
Year 3= 56,600 - 226,400= -169,800
Year 4= 56,600 - 169,800= -113,200
Year 5= 56,600 - 113,200= -56,600
Year 6= 56,600 - 56,600= 0
It will take exactly 6 full years to cover for the initial investment.
A company would like to evaluate two incentive schemes that take effect once the worker exceeds standard performance. In the first case the benefits are split 30% to the worker and 70% to the company up to 120% performance. If the worker exceeds 120% performance, all of the earnings go to the worker. In the second case, all earnings beyond standard performance are split 50/50 between the worker and the company.
a. Plot the earnings for each scheme.
b. Derive the equations for worker earnings and normalized unit labor costs for each scheme
c. Find the point at which the two plans break even.
d. Which do you think would the company prefer?
Answer:
B) plan 1 : worker earning y = x - 0.14 , unit labor = [tex]\frac{x-(0.14)}{x}[/tex]
plan 2 : worker earning y = 0.5x + 0.5, unit labor = (0.5x + 0.5) / x
C) At 128%
D ) plan D IS PREFERABLE
Explanation:
In the first case Benefits are split : 30% to worker , 70% to company ( up to 120% ) performance
In the second case benefits 50% go to the worker and 50% go the company
B) The equations for worker earnings and normalized unit labor costs for each scheme
Plan 1 :
y ( percentage earning of worker ) = 1
unit labor cost = Y / 1
y = 0 - 30
unit labor = 0.3 / x
y = x - 0.14 therefore unit labor = [tex]\frac{x-(0.14)}{x}[/tex]
plan 2 :
y ( percentage earning of worker ) = 1, y = 0.5x + 0.5
unit labor cost : Y / 1 = (0.5x + 0.5) / x
C ) The point at which the two plans break even
0.5x + 0.5 = x - 0.14
0.5 + 0.14 = x - 0.5x
0.64 = x(1 - 0.5 )
x = 0.64 / 0.5 = 1.28 = 128%
D) The company would prefer plan 1
Webster Corporation's monthly projected general and administrative expenses include $5,600 administrative salaries, $3,000 of other cash administrative expenses, $1,650 of depreciation expense on the administrative equipment, and .5% monthly interest on an outstanding bank loan of $16,000. Compute the total general and administrative expenses to be reported on the general and administrative expense budget per month.
Answer:Total general and administrative expenses budget per month =$10,250
Explanation:
Total general and administrative expenses are the compulsory costs to ensure that a company's day to day operations is maintained whether or not the company is making profit.
General and administrative expenses includes Rent, Utility bills, insurance wages and benefits, depreciation of office furnitures, Office supplies and are regarded as operating expenses and therefore interest paid on a bank loan is not an operating expenses but a financing activities and will not be considered as an administrative expense.
Administrative expenses= administrative Salaries+Other cash administrative expenses+Depreciation
=$5,600+$3,000+$1,650
=$10,250
The internal rate of return method is used to analyze a $831,500 capital investment proposal with annual net cash flows of $250,000 for each of the six years of its useful life. a. Determine a present value factor for an annuity of $1, which can be used in determining the internal rate of return. Carry your answer out to three decimal places.
Answer:
annuity factor for 20% and 6 periods = 3.326
Explanation:
the IRR represents the discount rate at which a project's NPV = 0
NPV = initial outlay + PV of future cash flows
NPV = 0
initial outlay = -$831,500
PV of future cash flows = $831,500 = cash flow x annuity factor
annuity factor = $831,500 / $250,000 = 3.326
using an annuity table and looking for the annuity factors for 6 periods, we find that the annuity factor for 20% and 6 periods = 3.326.
So our IRR = 20%
Handbags, Inc. had 200 units of inventory on hand at the end of the year. These were recorded at a cost of $18 each using the last−in, first−out (LIFO) method. The current replacement cost is $16 per unit. The selling price charged by Handbags, Inc. for each finished product is $27. In order to record the adjusting entry needed under the lower−of−cost−or−market rule, the Cost of Goods Sold will be ________.
Answer:
debited by $400
Explanation:
Inventory on hand at the beginning × each inventory cost
= 200 units × $18
= $3,600
Inventory on hand at the beginning × Current replacement cost
= 200 units × $16 per unit
= $3,200
Therefore;
$3,600 - $3,200 = $400 increase of cost of goods sold which is debit.
Miss. Asma works as a sales executive at HBL Bank, is upset at the way her manager, Sadaf, always calls her in for one-on-one meetings to discuss her underperformance. Though Asma makes a higher number of sales calls and works longer hours than last year, her sales figures are still low. She knows that the main reason behind her underperformance is the recent economic meltdown in the country. However, her manager feels that Asma's underperformance is the result of her laid-back attitude and has nothing to do with external factors. In this situation, what kind of behavior/Attitude Sadaf is showing and how it can be replicate
Answer:
Sadaf's behavior exemplifies Fundamental attribution error.
It can be replicated if Sadaf does not try to understand Asma's point of view of her underperformance.
Explanation:
The Fundamental Attribution Error is a type of error by the people of over-emphasizing the characteristics of a person while ignoring the situational factors. In such type of cognitive bias, people tend to instil the personal trait of other or judging them for their laid-back behavior based on their personal trait rather than thinking of any possibility of external situation that may have caused it.
In the given situation, Sadaf is showing fundamental attribution error behavior by instilling to Asma's underperformance with her laid-back behavior instead of asking her the real problem.
This attribution error can be replicated if Sadaf did not ask Asam for the reason behind her underperformance.
David Ortiz Motors has a target capital structure of 45% debt and 55% equity. The yield to maturity on the company's outstanding bonds is 12%, and the company's tax rate is 40%. Ortiz's CFO has calculated the company's WACC as 11.35%. What is the company's cost of equity capital
Answer:
the company's cost of equity capital is 14.75 %.
Explanation:
WACC = ke × (E/V) + kd × (D/V)
Where,
ke = cost of equity
= this is unknown
E/V = Weight of Equity
= 55%
kd = cost of debt
= Interest × ( 1 - tax rate)
= 12% × ( 1 - 0.40)
= 7.20 %
D/V = Weight of Debt
= 45%
Therefore,
WACC = ke × (E/V) + kd × (D/V)
11.35% = 55%ke + 7.20 % × 45%
11.35% = 55%ke + 3.24 %
55%ke = 8.11 %
ke = 14.75 %

Faisal has in his savings account and can save an additional per year. If interest rates are 12%, how long will it take his savings to grow to ?
Answer:
5 years and 4 months = 5.33 years
Explanation:
the question is incomplete and it is missing several numbers. I found the following question which I think is the complete:
"Faisal has $12,000 in his savings account and can save an additional $3600 per year. If interest rates are 12%, how long will it take his savings to grow to $47,000? "
by the end of year 1, Faisal will have:
$12,000 x (1 + 12%) = $13,440+ $3,600total = $17,040by the end of year 2, Faisal will have:
$17,040 x (1 + 12%) = $19,084.80+ $3,600total = $22,684.80by the end of year 3, Faisal will have:
$22,684.80 x (1 + 12%) = $25,406.98+ $3,600total = $29,066.98by the end of year 4, Faisal will have:
$29,066.98 x (1 + 12%) = $32,487.81+ $3,600total = $36,087.81by the end of year 5, Faisal will have:
$36,087.81 x (1 + 12%) = $40,418.35+ $3,600total = $44,018.35Since Faisal is very close to his goal, we can calculate how much money he will have in 6 months:
in 5 years and 6 months, Faisal will have:
$44,018.35 x (1 + 6%) = $46,659.45+ $1,800total = $48,459.45Faisal's savings are too high in 6 more months, so we can calculate in 3 more months instead:
in 5 years and 3 months, Faisal will have:
$44,018.35 x (1 + 3%) = $45,338.90+ $900total = $46,238.90Faisal is just a little bit short:
in 5 years and 4 months, Faisal will have:
$44,018.35 x (1 + 43%) = $45,779.08+ $1,200total = $46,979.08I guess we are close enough because in one more month he will have a significantly higher amount.

Kosher Pickle Company acquires all the outstanding stock of Midwest Produce for $12.5 million. The fair value of Midwest's assets is $8.5 million. The fair value of Midwest's liabilities is $1.3 million. Calculate the amount paid for goodwill
Answer:
$5.3 million
Explanation:
Kosher pickle company acquires outstanding stock of Midwest produce for $12.5 million
Fair value of Midwest assets is $8.5 million
Fair value of Midwest liabilities is $1.3 million
The first step is to calculate the fair value of net identifiable assets
= $8.5 million-$1.3 million
=7.2 million
Therefore, the amount paid for goodwill can be calculated as follows
= $12.5 million-$7.2 million
= $5.3 million
Hence the amount paid for goodwill is $5.3 million
The ________ is the pipeline through which products, their ownership, communication, financing and payment, and risk flow to the consumer.
Answer: Marketing channel
Explanation: The marketing channel is simply the pipeline through which products, their ownership, communication, financing and payment, and risk flow to the consumer. It is defined as a set of interdependent organizations that help ease the transfer of ownership as products move from producer to business user or consumer thereby creating a continuous and seamless supply chain. They help facilitate the physical flow of goods through the supply chain,and in the marketing mix represents "place" or "distribution".
A single-channel queuing system has an average service time of eight minutes and an average time between arrivals of 10 minutes. The arrival rate is: Group of answer choices 10 per hour. 12.5 per hour. 6 per hour. 7.5 per hour. 8 per hour.
The correct answer is B. 6 per hour
Explanation:
The term "arrival rate" refers to the number of customers that arrive at a business during a specific time such as an hour or a day. This is determined by how often customers arrive or the time between arrivals. This concept complements the service rate, which refers to the customers that receive a service during a period of time.
In the case presented, it is known the time between arrivals is 10 minutes, this means it is expected every 10 minutes a new customer arrives. Based on this, each hour the business can expect a total of 6 customers as 60 minutes divided by 10 (time between arrivals) = 6 customers. Thus, the rate of arrival is 6 per hour.
Sheffield Auto Supply does not segregate sales and sales taxes at the time of sale. The register total for March 16 is $19,902. All sales are subject to a 7% sales tax. Compute sales taxes payable. Sales taxes payable
Answer:
Sales tax = Total sales / 100 + Sales Tax rate * Sales Tax rate
Sales tax = {$19,902 / (100 + 7)} * 7
Sales tax = ($19,902 / 107) * 7
Sales tax = $1,302
Date Account Title and Explanation Debit Credit
Cash $19,902
Sales Tax payable $1,302
Sales revenue $18,600
($19,902 / 107 * 100)
(To record sales and sales taxes payable)
Answer:
1,302
Explanation:
Sales without tax x (100%+sales tax rate) = sales with tax
sales without tax x 1.07 (100%+7%) = 19902
sales without tax = 19902/1.07
sales without tax = 18600
sales with tax - sales without tax = sales tax payable
19902 - 18600 = 1302
A stock has an expected return of 13.5 percent, its beta is 1.40, and the expected return on the market is 11.5 percent. What must the risk-free rate be? (Do not round intermediate calculations and enter your answer as a percent rounded to 2 decimal places, e.g., 32.16.)
Answer:
The risk free rate is 6.50%
Explanation:
The required rate of return is the minimum return that investors demand/expect on a stock based on the systematic risk of the stock as given by the beta. The expected or required rate of return on a stock can be calculated using the CAPM equation.
The equation is,
r = rRF + Beta * (rM - rRF)
Where,
rRF is the risk free rate rM is the return on market
As we know the figures for r, Beta and rM, we will input these figures in the equation to calculate risk free rate.
Let risk free rate be x.
0.135 = x + 1.4 * (0.115 - x)
0.135 = x + 0.161 - 1.4x
0.135 - 0.161 = x - 1.4x
-0.026 = -0.4x
-0.026 / -0.4 = x
x = 0.065 or 6.50%
r = 0.1475 or 14.75%
A stock had returns of 9.62 percent, −14.65 percent, 19.85 percent, 25.35 percent, and 7.65 percent over the past five years. What was the geometric average return for this stock?
Answer:
The geometric average return for this stock was 8.64%.
Explanation:
Geometric average return refers to the return which will result in the correct compounded dollars at the end of the time period.
Geometric average return can be computed using the following formula:
Geometric average return = {[(1 + r1)(1 + r2) ... (1 + rn)]^(1/n)} - 1 ......... (1)
Where r is returns from year 1 to year n.
For the stock in the question, we have:
r1 = 9.62%, 0.0962
r2 = -14.65%, or -0.1465
r3 = 19.85%, or 0.1985
r4 = 25.35%, or 0.2535
r5 = 7.65%, or 0.0765
n = 5
Substituting the values into equation (1), we have:
Geometric average return = {[(1 + 0.0962)(1 - 0.1465)(1 + 0.1985)(1 + 0.2535)(1 + 0.0765)]^(1/5)} - 1
Geometric average return = {1.51310732605096^0.20} - 1
Geometric average return = 0.0864, or 8.64%
Therefore, the geometric average return for this stock was 8.64%.
Which of the following is not a factor that a manager should bear in mind when estimating a project's revenues and costs?
A) Sales of a product will typically accelerate, stabilize, and then decline as the product becomes outdated or faces increased competition.
B) A new product typically has its highest sales immediately after release as customers are attracted by the novelty of the product.
C) The prices of technology products tend to fall over time as newer, superior technologies emerge and production costs decline.
D) Prices and costs tend to rise with the general level of inflation in the economy.
Answer:
B) A new product typically has its highest sales immediately after release as customers are attracted by the novelty of the product.
Explanation:
When a manager is implementing and executing a project, there are certain factors to be considered for revenue and costs associated with the project.
For instance, that a new product typically has its highest sales immediately after release as customers are attracted by the novelty of the product is not a factor that a manager should bear in mind when estimating a project's revenues and costs. This is simply because it is not guaranteed that all new products introduced to the market would be accepted or attractive to customers due to economical factors such scale of preference and opportunity costs.
Ideally, the factors to be considered by a manager when estimating a project's revenues and costs are;
1. Sales of a product will typically accelerate, stabilize, and then decline as the product becomes outdated or faces increased competition.
2. The prices of technology products tend to fall over time as newer, superior technologies emerge and production costs decline.
3. Prices and costs tend to rise with the general level of inflation in the economy.
