A machine costing $208,400 with a four-year life and an estimated $18,000 salvage value is installed in Luther Companys factory on January 1. The factory manager estimates the machine will produce 476,000 units of product during its life. It actually produces the following units: 122,800 in 1st year, 123,300 in 2nd year, 120,600 in 3rd year, 119,300 in 4th year. The total number of units produced by the end of year 4 exceeds the original estimatethis difference was not predicted. (The machine must not be depreciated below its estimated salvage value.)
