Problem 10-2A Depreciation methods LO P1 A machine costing $206,600 with a four-year life and an estimated $15,000 salvage value is installed in Luther Company's factory on January 1. The factory manager estimates the machine will produce 479,000 units of product during its life. It actually produces the following units: 121,600 in 1st year, 124,300 in 2nd year, 120,400 in 3rd year, 122,700 in 4th year. The total number of units produced by the end of year 4 exceeds the original estimate-this difference was not predicted. (The machine must not be depreciated below its estimated salvage value.)
