A machine costing $214,400 with a four-year life and an estimated $18,000 salvage value is installed in Luther Company's factory on January 1. The factory manager estimates the machine will produce 491,000 units of product during its life. It actually produces the following units: 122,500 in 1st year, 124,000 in 2nd year, 121,500 in 3rd year, 133,000 in 4th year.
