Your firm needs a machine which costs $50,000, and requires $2,000 in maintenance for each year of its five-year life. After five years, this machine will be replaced. The machine falls into the MACRS five-year class life category. Assume a tax rate of 21 percent and a discount rate of 10 percent. If this machine can be sold for $3,000 at the end of year 5, what is the after-tax salvage value?
