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 10% return. (For example, if you bought a 737 for $1979 million at the start of year 1 and sold it a year later your total profit would be 18.04-373 - 19.79 = $1.98 million, 10% of the purchase cost.) Assume airlines write off their aircraft straight-line over 15 years to a salvage value equal to 20% of the onginal cost.
