In each of the following Home Depot proposals determine the number of years that the given end-of year-cash flow must continue to provide the given rate of return on the given initial amount.

Case                Initial amount                  Annual cash flow               Rate of return                

A                 $   1,000                            $ 250                                     11%

B                      150,000                             30,000                                15

C                      80,000                               10.000                                 10

D                      600                                    275                                       9

E                     17,000                               3.500                                    5

Explanation / Answer

1) F = A [ ( 1+r)n -1 ] / r

1000 = 250 [ ( 1+0.11)n -1] / 0.11

110 = 250 [ 1.11n -1]

1.11n- 1 = 0.44

1.11n = 1.44

n log 1.11 = log 1.44

n = 3.49 years

2) 150,000 = 30,000 [ ( 1+0.15)n -1] / 0.15

22500 = 30,000 [ ( 1+0.15)n -1]

(1+0.15)n -1 = 0.75

1.15n = 1.75

n = 4 years

3) 80,000 = 10,000[ ( 1+0.1)n -1] / 0.10  

8000 = 10,000 [ 1.1n -1]

1.1n = 1.8

n = 6.16 years

4) 600 = 275 [ ( 1+0.09)n -1] / 0.09

54 = 275[ ( 1.09n -1)]

n = 2.08 years

5) 17,000 = 3500 [ ( 1+0.05)n -1] / 0.05

850 = 3500 [ 1.05n -1]

n = 4.45 years.
