6 You are considering investing in a company that makes cell phones. It will take three years for the business to sell its first product. You can expect to make $600k in years 3, 4, 5 and 6. Your return on alternative investments is 6%. How much can you afford to invest ?

(C) $1.75 million
(D) You should not buy the business at any price
7 You loan $2,000 to a friend. How would you calculate the annual payments you should receive in each of the next 6 years if the interest rate is 6% ? There are two correct answers.

(C) $2,000(PV/A, 6%,6)
(D) $2,000(FV/PV, 6%,6)
(E) $2000(FV/PV, 6%, 6)(A/PV, 6%, 6)
8 What is the best decision criteria?
(A) NPV
(B) PI
(C) IRR
(D) Discounted PI
(E) Flip a coin
9 You are given a choice between Plan 1: $2,000 a year from now and $1,000 in two years OR Plan 2: $1,000 a year from now and $2,000 in two years. The interest rate is the same in both plans. Which has the higher PV ?
(A) Plan 1
(B) Plan 2
(C) Plans 1 and 2 are equivalent
(D) It depends on the interest rate
10 The IRR of a project is 10%. What is the project's NPV if alternative investments have a 10% return?
(A) 10%
(B) At least $1,000
(C) A negative number
(D) Zero
11 A project has an NPV of $1,250 at 10%. If you were to calculate the projects IRR, you should get a number bigger than 10% ?
True False
12 A project has an NPV of $1,250 at 10%. If you were to calculate the Project's PI, will you get a number bigger than 1 ?
Yes No
13 Calculate the after tax cash flow if you know the revenues for a business are $2.5 million, operating costs of $1.5 million, a marginal tax rate of 45% and depreciation of $1 million?
(A) $500k
(B) $750k
(C) $1 million
(D) $1.25 million
14 For the information in problem 13. If the revenue for the business increase and everything else stays the same, you would expect the after tax cash flow to:
(A) Increase
(B) Decrease
15 For the information in problem 14. If the operating costs go up for the business increase and everything else stays the same, you would expect the after tax cash flow to:
(A) Increase
(B) Decrease
16 For the information in problem 14. If the marginal tax rate increases and everything else stays the same, you would expect the after tax cash flow to:
(A) Increase
(B) Decrease
17 A project has an investment of $10,000. It returns $250 in each of the next40 years ! You are to do an IRR calculation. As you know the calculation involves trial and error. Is a good first guess at the IRR given by IRR = $250/$10,000 = 2.5%?
Yes No
18 A project has an investment of $1000 and returns of $300 in each of years 1, 2, 3 and 4. A reasonable estimate of the IRR is (Hint: Use the tables in the back of the book):
(A) Between 4 and 5 %
(B) Between 5 and 6%
(C) Between 6 and 7 %
(D) Between 7 and 8 %
(E) Between 8 and 9 %.
