Your firm needs a computerized machine tool lathe which costs $$50,000$ and requires $$12,000$ in maintenance for each year of its $3-$

year life. After three years, this machine will be replaced. The machine falls into the MACRS $3-$year class life category, and neither

bonus depreciation nor Section $179$ expensing can be used. Assume a tax rate of $21$ percent and a discount rate of $12$ percent.

Calculate the depreciation tax shield for this project in year $3.$
