Assume that at the beginning of 2009, a company purchased a used jet at a cost of $44,400,000. The plane expects to remain useful for five years (6.5 million miles) and to have a residual value of $5,400,000. Fast Delivery expects to fly the plane 725,000 miles the first year, 1,225,000 miles each year during the second, third, and fourth years, and 2,100,000 miles the last year.
