The table given below shows how, on average, the market value of a Boeing 737 has varied with its age and the cash flow needed in each year to provide a 13% return. (For example, if you bought a 737 for $19.93 million at the start of year 1 and sold it a year later, your total profit would be 18.11 + 4.41 19.93 = $2.59 million, 13% of the purchase cost.) Assume airlines write off their aircraft straight-line over 15 years to a salvage value equal to 10% of the original cost.

Start of Year	Market Value	Cash Flow
1	19.93
2	18.11	4.41
3	17.03	3.43
4	15.90	3.34
5	15.13	2.84
6	14.21	2.89
7	13.60	2.46
8	12.80	2.57
9	12.29	2.17
10	11.58	2.31
11	11.15	1.94
12	10.51	2.09
13	10.15	1.73
14	9.56	1.91
