Differential Analysis for Machine Replacement Boyer Digital Components Company assembles circuit boards by using a manually operated machine to insert electronic components. The original cost of the machine is $70,200, the accurnulated depreciation is $28,100, its remaining useful life is five years, and its residual value is negligible. On May 4 of the current year, a proposal was made to replace the present manufacturing procedure with a fully automatic machine that has a purchase price of $146,000. The automatic machine has an estimated useful life of five years and no significant residual value. For use in evaluating the proposal, the accountant accumulated the following annual data on present and proposed operations: a. Prepare a differential analysis dated May 4 to determine whether to continue with the old machine (Alternative 1) or replace the old machine (Altemative 2). Prepare the analysis over the useful life of the new machine. If an amount is zero, enter " 0 ". If required, use a minus sign to indicate a loss. a.
