Nike has so far had $30,000,000 in losses at its shoe factory in Vietnam in 2017. The additional revenue that it will earn from producing an additional shoe is $100 while the additional cots incurred for that additional shoe is $99.99. Should Nike continue operations in that factory and produce that additional shoe
Answers
Answer: c. Yes, because the marginal revenue from producing the additional shoe is greater than the marginal costs.
Explanation:
When making financial decisions, companies abide by the principle of Sunk Costs. This means that money that has already been spent, should not have any effect on future financial decisions. The $30 million that has been lost already will therefore not be considered.
The only figures now are the additional cost and revenue. The additional revenue is more than the additional cost so this shoe should be produced because it brings in a profit of $0.01.
Which theory would most likely explain why a commercial bank, which usually focuses on short-term securities, would switch to long-term securities due to a change in interest rates. pure expectation liquidity premium segmented market preferred habitat
Answers
Answer:
preferred habitat
Explanation:
According to the preferred habitat theory, if the expected returns from investment of a particular investment maturity is large enough, investors would shift from their preferred maturities.
In this question, there is a shift from the preferred maturity (short-term securities) to a long-term securities when interest rate changes
The pure expectations theory assumes that bonds of any maturity are perfect substitutes for each other. For example, if an investor buys a 10 year bond and holds it for 1 year, the return is the same as buying a 1 year bond. The theory also assumes that risk premium does not exist and a security only earns its risk free rate
Liquidity premium theory states that risk premium increases with the maturity of a bond. The theory predicts that the yield curve is upward sloping due to liquidity premium
According to the segmented market theory, each bond maturity segment can be thought of as a segment market in which yield are a function of the demand and supply for funds in that maturity.

Answer:
1a. Product cost per unit if absorption costing is used by the company is $82 per unit.
1b. Net operating income if absorption costing is used by the company is $774,000.
2a. Product cost per unit if variable costing is used by the company is $72 per unit.
2b. Net operating income if variable costing is used by the company is $694,000.
Explanation:
1a. Assume the company uses absorption costing. Determine its product cost per unit.
Fixed overhead per unit = Fixed overhead for the year / Units produce for the year = $420,000 / $42,000 = $10
Product cost per unit = Direct materials per unit + Direct labor per unit + Variable overhead per unit + Fixed overhead per unit = $48 + $18 + $6 + $10 = $82
Therefore, product cost per unit if absorption costing is used by the company is $82 per unit.
1b. Assume the company uses absorption costing. Prepare its income statement for the year under absorption costing.
Note: See number 1b of the attached excel file for the income statement for the year under absorption costing.
From number 1b of the attached excel file, we have:
Net operating income = $774,000
Therefore, net operating income if absorption costing is used by the company is $774,000.
2a. Assume the company uses variable costing. Determine its product cost per unit.
Product cost per unit = Direct materials per unit + Direct labor per unit + Variable overhead per unit = $48 + $18 + $6 = $72
Therefore, product cost per unit if variable costing is used by the company is $72 per unit.
2b. Assume the company uses variable costing. Prepare its income statement for the year under variable costing.
Note: See number 2b of the attached excel file for the income statement for the year under variable costing.

What is the initial selling price needed to obtain a target profit of $50,000 using the manufacturing cost markup method
Answers
Answer:
$15 per unit
Explanation:
Note "The full question is attached as picture below"
Markup = (Fixed Costs + Desired Profit) / Units produced
Markup = ($300,000 + $150,000 + $50,000) / 50,000
Markup = $500,000 / 50,000 units
Markup = $10 per unit
Variable cost per unit = Variable cost / Quantity
Variable cost per unit = ($200,000 + $50,000) / 50,000
Variable cost per unit = $5 per unit
Sales price = Variable cost + Markup
Sales price = $5 per unit + $10 per unit
Sales price = $15 per unit
So, the initial selling price needed to obtain a target profit of $50,000 using the manufacturing cost markup method is $15 per unit.

Answers
Answer: c) Latency between her VPN client removing encryption and making it available to the video-conferencing client is causing poor performance.
Explanation:
A Virtual Private Network (VPN) is used to protect the identity of people online as it encrypts a person's data and uses different servers to allow them browse the web and with a different IP address from the user's original IP address that way it appears as though the user is somewhere else in the world than they actually are.
In doing this however, VPNs might give slow speeds due to the latency that develops as the VPN encrypts and decrypts data for use. In this case, the VPN latency in decrypting the video call for Consuela to see it is slowing down the speed of the Video conferencing client.

b. Three quarters of the experts (group B) assume that the tsunami will come with a 10 percent probability.

I would believe group A more
because, as we know "Precaution is always better an cure"

I chose group A because
even if the tsunami ain't powerful enough, I would be glad I was careful enough for it and it'll help me in future if I face another situation like this again
The consequences if I chose group B would be :
well, if I would have chose B, I won't have taken any Precautions at all
I won't have been careful enough
and in case their prediction went wrong, I would have to suffer high losses.

Test Tech has preferred stock outstanding that pays an $10.85 annual dividend. It price is $125. What is the required rate of return on the preferred stock
Answers
Answer:
8.7%
Explanation:
Calculation to determine the required rate of return on the preferred stock
Using this formula
Required rate of return=Annual dividend/Price
Let plug in the formula
Required rate of return=$10.85/$125
Required rate of return=0.087*100
Required rate of return=8.7%

A consumer has $180 in monthly income to spend on two goods, D and G, where D is on the y-axis. The price of good D, PD is $6, and the marginal rate of transformation is -2. How many units of good G can be purchased if all income is used to purchase good G
Answers
Answer:
The number of units of good G that can be purchased if all income is used to purchase good G is 15 units.
Explanation:
Since D is on the y-axis, indicating G is on the x-axis, the formula for calculating the marginal rate of transformation (MRT) is given as follows:
MRT = - PG / PD …………………. (1)
Where:
MRT = Marginal rate of transformation = -2
PG = Price of good G = ?
PD = Price of good D = $6
Substituting the relevant values into equation (1) and solve for PG, we have:
-2 = - PG / $6
PG = -2 * (-6) = $12
Therefore, we have:
Number units of good G if all income is spent on it = Monthly income / PG = $180 / $12 = 15
Therefore, the number of units of good G that can be purchased if all income is used to purchase good G is 15 units.
Suppose that the U.S. government decides to charge wine producers a tax. Before the tax, 40 billion bottles of wine were sold every year at a price of $7 per bottle. After the tax, 35 billion bottles of wine are sold every year; consumers pay $9 per bottle, and producers receive $6 per bottle (after paying the tax). The amount of the tax on a bottle of wine isper bottle. Of this amount, the burden that falls on consumers isper bottle, and the burden that falls on producers isper bottle. True or False: The effect of the tax on the quantity sold would have been larger if the tax had been levied on consumers.
Answers
Answer and Explanation:
The computation is shown below:
The amount of the tax for the wine bottle is
= $9 per bottle - $6 per bottle
= $3 per bottle
Before the tax, the price per bottle is $7 per bottle
The Tax burden on consumers is
= $9 - $7
= $2 per bottle
And, the tax burden on producers is
= $7 per bottle - $6 per bottle
= $1 per bottle
So, the given statement is false as the impact would remain the same whether it is for producer or consumer

Answers
Answer:
The Present Worth of the machine if the real interest rate is 10% per year and the inflation rate is 5% per year, using:
(a) constant-value dollars
= $10,518.60
(b) then-current dollars
= $10,818.65
Explanation:
a) Data and Calculations:
Cost a certain machine six years from now = $25,000
Time period = 6 years
Real interest rate = 10%
Inflation rate = 5%
Nominal interest rate = 5% (10% - 5%)
Discount factor at 10% for 6 years = 0.564
Discount factor at 5% for 6 years = 0.746
PW using:
a) Constant-value dollars = $18,650 ($25,000 * 0.746)
PW = $10,518.60 ($18,650 * 0.564)
b) Then-current dollars:
The nominal rate = 0.1 + 0.05 + (0.1 * 0.05) = 0.155
$10,818.65 ($25,000 * 0.432746)

Burnham Brothers, Inc. has no retained earnings since it has always paid out all of its earnings as dividends This same situation is expected to persist in the future. The company uses CAPM to calculate its cost of equity and its target capital structure consists of common stock, preferred stock, and debt. Which of the following events would reduce its WACC?
a. The flotation costs associated with issuing new common stock increase.
b. The company's beta increases.
c. Expected inflation increases.
d. The market risk premium declines.
Answers
Answer: d. The market risk premium declines.
Explanation:
The Weighted Average Cost of Capital (WACC) takes into account the cost of equity and debt which means that if either of these costs increase, the WACC will increase as well and if any decrease, WACC will follow suit.
Market risk premium is used in the calculation of the cost of equity when using CAPM in the following manner:
= Risk free rate + Beta * Market risk premium
As can be inferred from the above formula, if the market risk premium declines, a lower cost of equity will result which would then reduce the WACC as well.

Differentiate between a defined contribution pension plan and a defined benefit pension plan. Explain how the employer's obligation differs between the two types of plans.
Answers
Answer:
Differences Between a Defined Contribution Pension Plan and a Defined Benefit Pension Plan.
With a defined contribution pension plan, the benefit that will accrue to the employee is not known or defined ahead of her retirement. But the contributions that will be made by the employer and the employee to fund the pension are clearly spelt out.
With a defined benefit pension plan, the benefit (i.e. the monthly payment to the retiree) is stated ahead of the pension time. It is based on the employee's tenure and salary. Employees do not contribute to the plan but are entitled to lifetime monthly payments.
Explanation:
The employer and each employee contribute some certain percentages to each worker's individual retirement account (IRA) under the defined contribution pension plan. Under the defined benefit pension plan, the employer is solely responsible for funding the plan and the employee benefits via a monthly payment from the funding plan during retirement.

d. 17
Explanation:
The computation is shown below;
Here the time started i.e. t=0
Therefore there was no customer upto t=5 hour
At t=5
The client first came and as there was no other customer available so we begins service to customer 1
Now
As service off is 4 hour so service to client 1 will end at
t=9 hour.
Also mid-time at t = 6
That means the client 2 came and at t = 8 the client 3 came.
Now at t = 9 the service begins for client 3 and end at t = 13 ( 9 + 4)
At t=13 hour, so after four hours it should be 17
