A machine costing $210,200 with a four-year life and an estimated $17,000 salvage value is installed in Luther Company's factory on January 1. The factory manager estimates the machine will produce 483,000 units of product during its life. It actually produces the following units: 123,000 in 1st year, 122,700 in 2nd year, 121,200 in 3rd year, 126,100 in 4th year.
