The Mighty Mouse Computer company is considering whether or not to install a packaging robot. The robot costs $500,000, including shipping and installation. The robot can be depreciated using MACRS as a five-year asset. (MACRS depreciation rates for a fiveyear asset: 20%, 32%, 19.2%, 11.52%, 11.52%, and 5.76%.) The robot is expected to last for five years, at which time management expects to sell it for parts for $100,000. The robot is expected to replace five employees in the shipping department, saving the company

$150,000 each year. Mighty’s tax rate is 30%.
