SOLUTIONS TO END-OF-CHAPTER PROBLEMS

10-1

NPV = -\$40,000 + \$9,000[(1/I) – (1/(I × (1 + I)N)]
= -\$40,000 + \$9,000[(1/0.11) – (1/(0.11 × (1 + 0.11)7)]
= \$2,409.77.
Financial calculator solution: Input CF0 = -40000, CF1-7 = 9000, I/YR = 11, and then
solve for NPV = \$2,409.77.

10-2

Financial calculator solution: Input CF0 = -40000, CF1-8 = 9000, and then solve for IRR =
12.84%.

Financial calculator: Obtain the FVA by inputting N = 7, I/YR = 11, PV = 0, PMT =
9000, and then solve for FV = \$87,049. The MIRR can be obtained by inputting N = 7,
PV = -40000, PMT = 0, FV = 88049, and then solving for I/YR = 11.93%.

PV = \$9,000[(1/I) – (1/(I × (1 + I)N)]
= \$9,000[(1/0.11) – (1/(0.11 × (1 + 0.11)7)]
= \$42,410.
Financial calculator: Find present value of future cash flows by inputting N = 7, I/YR =
11, PMT = -9000, FV = 0, then solve for PV = \$42,409.
PI = PV of future cash flows/Initial cost
= \$42,409/\$40,000 = 1.06.

10-5

Since the cash flows are a constant \$9,000, calculate the payback period as:
\$40,000/\$9,000 = 4.44, so the payback is about 4 years.

a. Project A: Using a financial calculator, enter the following:
CF0 = -15000000
CF1 = 5000000
CF2 = 10000000
CF3 = 20000000
I/YR = 10; NPV = \$12,836,213.
Change I/YR = 10 to I/YR = 5; NPV = \$16,108,952.
Change I/YR = 5 to I/YR = 15; NPV = \$10,059,587.
Project B: Using a financial calculator, enter the following:
CF0 = -15000000
CF1 = 20000000
CF2 = 10000000
CF3 = 6000000
I/YR = 10; NPV = \$15,954,170.
Change I/YR = 10 to I/YR = 5; NPV = \$18,300,939.
Change I/YR = 5 to I/YR = 15; NPV = \$13,897,838.
b. Using the data for Project A, enter the cash flows into a financial calculator and solve
for IRRA = 43.97%. The IRR is independent of the WACC, so IRR doesn’t change
when the WACC changes.
Using the data for Project B, enter the cash flows into a financial calculator and solve
for IRRB = 82.03%. Again, the IRR is independent of the WACC, so IRR doesn’t
change when the WACC changes.
