First-Rate Cleaners is considering replacing one of its tired cleaning machines for a new model that can dry-clean clothes in half the time of the old machine. Beth the book value and the salvage value of the current machine are $2,500; the current machine would be sold if the new machine is purchased. The new machine would cost $20,000 and is expected to last 15 years, at which point it would be sold for its salvage value of $2,000. It would generate additional net operating cash flows of $4,500 each year of its useful life. FirstRate Cleaners estimates its tax rate to be 25%, while its required rate of return is 8%.
