Question - A machine costing $212,000 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 485,000 units of product during its life. It actually produces the following units: 122,800 in 1st year, 122,800 in 2nd year, 120,000 in 3rd year, 129,400 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.)
Required: Compute depreciation for each year (and total depreciation of all years combined) for the machine under each depreciation method.
