XYZ purchased a machine 5 years ago at a cost of $95,000. The machine had an expected life of 10 years at the

time of purchase, and it is being depreciated by the straight-line method by $9,500 per year. The old machine

can be sold today for $65,000. If the machine is not replaced, it can be sold for $10,000 at the end of its useful

life.

A new machine can be purchased for $170,000, including installation costs. During its 5-year life, it will reduce

cash operating expenses by $55,000 per year. Sales are not expected to change. At the end of its useful life,

the machine is estimated to be worthless. The applicable depreciation rates are 33%, 45%, 15%, 7% and 0%.

The firm's tax rate is 40%. The WACC is 15%.

a. If the new machine is purchased, what is the amount of the initial cash flow at Year 0?

b. What are the incremental cash flows that will occur at the end of Years 1 through 5?

c. Should the old machine be replaced? Explain.
