Googly Coffees is considering the purchase of a special-purpose coffee machine for $65 000. It is expected to have a useful life of 4 years with no terminal disposal value. The manager estimates the following savings in cash operating costs:

Year	Amount
1	$25 000
2	22 000
3	21 000
4	20 000
Total	$88 000

Googly coffees uses a required rate of return of 18% in its capital budgeting decisions. Ignore income taxes in your analysis. Assume that all cash flows occur at year-end except for initial investment amounts. The manager is certain that the machine is a worthwhile investment since the savings are greater than the cost.
