The Darlington Equipment Company purchased a machines years ago at a cost of $80,000. 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 $8,000 per year. If the machine 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 $60,000 per year. Sales are not expected to change. At the end of its useful life, the machine is estimated to be worthless. MACRS depreciation will be used, and the machine will be depreciated over its 3-year class life rather than its 5-year economic life, so the applicable depreciated rates are 33%, 45%, 15%, and 7%. The old machine can be sold today for $60,000. The firm's tax rate is 40%. The appropriate WACC is 9%. a. If the new machine is purchased, what is the amount of the initial cash flow at year 0? Round your answer to the nearest dollar. Negative amount should be indication by a minus sign. $ v. What are the incremental net cash flows that will occur at the end of Year 1 through 57? C. What is the NPV of this project? $ Should Darlington replace the old machine
