Answer:
3.27
Explanation:
Calculation to determine the enterprise value-EBITDA multiple for this company
First step is to calculate the
Enterprise value
Using this formula
Enterprise value = Market Capitalization + Total Debt - Cash and equivalents
Let plug in the formula
Enterprise value=$582000 + $192000 - $21000
Enterprise value=$753000
Second step is calculate EBITDA using this formula
EBITDA = EBIT + Depreciation and Amortization
Let plug in the formula
EBITDA= $93000 + $137000
EBITDA=$230,000
Now let determine the EBITDA multiple using this formula
EBITDA multiple = Enterprise Value / EBITDA
Let plug in the formula
EBITDA multiple=$753000 / $230000
EBITDA multiple= 3.27
Therefore enterprise value-EBITDA multiple for this company is 3.27

($ in millions)CyberdyneVirtucon Net sales$39,905 $5,684 Net income 10,375 1,194 Operating cash flows 14,865 1,334 Total assets, beginning 58,905 15,184 Total assets, ending 60,905 14,884 Required: 1. Calculate the return on assets for both companies.
Answer:
Return on assets for Cyberdyne Systems and Virtucon are 0.2 and 0.1 respectively.
Explanation:
Return on asset is a measure of the ratio of the net income to the total average assets of an entity or organization. It givens and insight into the company's ability to generate profits from the use of its assets.
For Cyberdyne Systems, given that Net income $10,375 and the assets at the beginning and end of the period are $58,905 and $60,905
Total average assets = ($58,905 + $60,905)/2
= $59,905
Return on assets = $10,375/$59,905
= 0.17319088
To one decimal place = 0.2
For Virtucon, given that Net income $1,194 and the assets at the beginning and end of the period are 15,184 and 14,884
Total average assets = ($15,184 + $14,884)/2
= $15,034
Return on assets = $1,194/$15,034
= 0.079419981
To one decimal place = 0.1
The Bradley Corporation produces a product with the following costs as of July 1, 20X1: Material $4 per unit Labor 4 per unit Overhead 2 per unit Beginning inventory at these costs on July 1 was 3,500 units. From July 1 to December 1, 20X1, Bradley Corporation produced 13,000 units. These units had a material cost of $4, labor of $6, and overhead of $4 per unit. Bradley uses LIFO inventory accounting. a. Assuming that Bradley Corporation sold 15,000 units during the last six months of the year at $19 each, what is its gross profit
Answer: $83000
Explanation:
The gross profit will be:
Sales = 15000 × $19 = $285000
Less Cost of goods sold from new inventory = 13000 × $14 = $182000
Less Cost of goods sold from old inventory = 2000 × $10 = $20000
Total cost of goods sold = $182000 + $20000 = $202000
Gross profit = $285000 - $202000
Gross profit = $83000
You estimate that your cattle farm will generate $0.10 million of profits on sales of $2 million under normal economic conditions and that the degree of operating leverage is 5.a. What will profits be if sales turn out to be $1.6 million
Answer:
Profit would decrease to $0.0 million
Explanation:
The degree of operating leverage is the change in profit as a result of the change in sales revenue
DOL=% change in profit/% change in sales
DOL=5
% change in profit=unknown
% change in sales=($1.6m-$2.0m)/$2.0m
% change in sales=-20%
5=% change in profit/-20%
% change in profit=5*-20%
% change in profit=-100%
the new amount of profit=current amount of profit*(1-% change in profit)
current amount of profit=$0.10 million
the new amount of profit=$0.10 million*(1-100%)
the new amount of profit=$0.0 million

If your short-term interest rate (the rate on your current debt) is 12.1%, then your bond rate (the rate on your long-term debt) is:
Answer: 13.5% (14% higher than the current debt rate)
Explanation:
Since the short-term interest rate (the rate on your current debt) is 12.1%, then it should be noted that the rate on the long term debt will be higher than the rate on the short term debt.
The long term debt have a higher duration and therefore have a higher rate when compared to the short term debt. Therefore, the correct option will be 13.5% (14% higher than the current debt rate) since it's higher than the 12.1% given as the short term rate.

Jenny Enterprises has just entered a lease agreement for a new manufacturing facility. Under the terms of the agreement, the company agreed to pay rent of $12,500 per month for the next 10 years with the first payment due today. If the APR is 6.48 percent compounded monthly, what is the value of the payments today
Answer:
$1,107,793.41
Explanation:
The value of the payment today can be ascertained using the present value of an annuity due formula since the first payment is immediate as shown thus:
PV=monthly payment*(1-(1+r)^-n/r*(1+r)
monthly payment=$12,500
r=monthly interest rate=6.48%/12=0.0054
n=number of monthly payments in 10 year=10*12=120
PV=$12,500*(1-(1+0.0054)^-120/0.0054*(1+0.0054)
PV=$12,500*(1-(1.0054)^-120/0.0054*(1.0054)
PV=$12,500*(1-0.524003627 )/0.0054*1.0054
PV=$12,500*0.475996373 /0.0054*1.0054
PV=$1,107,793.41

E. Debit Pwork in Process lnventory 110,000, credit Factory Overhead $40000. credit Factory wages Payable $150000.
Answer: C. Debit Work in Process Inventory $110.000, debit Factory Overhead $40,000, credit Factory Wages payable $150,000
Explanation:
Minstrel incurred a factory payroll of $150,000 and $40,000 was indirect.
This $40,000 indirect payroll cost will be treated as Factory overhead and will be debited.
The remaining $110,000 is direct labor costs and it will be apportioned to inventory therefore it will be debited to the Work in Process account.
The total figure of $150,000 represents the amount that the company owes its factory staff so it will be credited to factory overhead to recognize it as a liability.

Coronado Company received proceeds of $209000 on 10-year, 5% bonds issued on January 1, 2016. The bonds had a face value of $220000, pay interest annually on January 1, and have a call price of 102. Coronado uses the straight-line method of amortization. Coronado Company decided to redeem the bonds on January 1, 2018. What amount of gain or loss would Coronado report on its 2018 income statement
Answer:
Coronado Company
The amount of gain or loss that Coronado would report on its 2018 income statement is:
= $13,200.
Explanation:
a) Data and Calculations:
Bonds proceeds = $209,000
Bonds face value = 220,000
Bonds Discounts = $11,000
Period of bonds = 10 years
Straight-line amortization = $1,100 annually
Interest payment = annually
Coupon rate rate = 5%
Fair value on January 1, 2017 = $210,100 ($209,000 + $1,100)
Fair value on January 1, 2018 = $211,200 ($210,100 + $1,100)
Call price = 102
Total call value (cash payment) = $224,400 ($220,000 * 102/100)
Loss to report on its 2018 income statement = $13,200 ($224,400 - $209,000 - $2,200)

A company rents a building with a total of 50,000 square feet, which are evenly divided between two floors. The company allocates the rent for space on the first floor at twice the rate of space on the second floor. The total monthly rent for the building is $30,000. How much of the monthly rental expense should be allocated to a department that occupies 10,000 square feet on the first floor
Answer:
$8,000
Explanation:
The computation of the monthly rental expense allocated is shown below:
Rent allocated to 1st floor:
= $30,000 × 2 ÷ 3
= $20,000
There is 50,000 square feet i.e. equally divided between first floor and second floor. so 25,000 square feet for each floor.

The Fed is independent of the U.S. Government but can still face significant pressure from the U.S. Government as it is the President that nominates the Board of Governors and the Senate confirms them.
Much like Justices on the Supreme Court who get their positions the same way, these governors have to be protected from being used as political pawns so they are given long terms in office to ensure that they can pursue an independent policy without having to worry about the current administration coming after them if they go contrary to its will.
At your new job you estimate that your average salary over your working years will be $95,000 per year. How many more years would you have to work to receive as much benefit from a flat benefit of $3,000 times years of service as you would receive from 3.75 percent of your average salary times years of service?
Answer:
1.1875 or 1.19 times
Explanation:
The calculation of the no of years is to be given below;
= 3.75 % of average salary × years of service = 3000 × years of service
So,
= 0.0375 × 95000 × years of service = 3000 × years of service
So, the years of service is
= 3562.5 ÷ 3000
= 1.1875 or 1.19 times
What do you call it when you don't invest in your new and smaller businesses?
Answer:
investment foe buisness
When you don't invest in your new and smaller businesses, it is called debt investment.
Debt investment basically means opting to use an amount borrowed to finance one's business (either big or small business). This investment refers to a scenario when an investor (i.e. banks) lend money to the entrepreneur with the expectation that the entrepreneur will pay-back the investment with interest.
This type of business running system is somewhat burdensome because of repayment of the loan with interest.
The advantage of this method of financing is that the capital is fully provided to the business owner.

Suppose that the firm pays its workers $46 per day. Each unit of output sells for $12. How many workers should the firm hire
Solution :
A firm hires labor till a point where the cost of hiring is equal to the value of the additional revenue it produces.
We know ,
the wage rate = cos of hiring an additional worker
the value of the additional revenue that the firm produces = price x (MPI) marginal product of the labor.
Therefore, the firm will hire when :
Wage = value of the additional revenue it generates
Thus, wage = price x (MPI) marginal product of the labor ...........(i)
Therefore, given :
wage of a worker = $ 45
Price = $ 12
So, 45 = 12 x MPI
MPI = 3.8
So the marginal product of employing three days of labor = 25-18/4-3 = 7
Marginal product of employing four days of labor = 30-25/4-3 = 5
So the 4th day produces less revenue than the cost that it generates.
So, the firm should hire 3 workers.
