Differential Analysis Report for Machine Replacement White Noise Technologies Inc. assembles circuit boards by using a manually operated machine to insert electronic components. The original cost of the machine is $80,400, the accumulated depreciation is $32,200, its remaining useful life is five years, and its residual value is zero. A proposal was made to replace the present manufacturing procedure with a fully automatic machine that will cost $151,200. 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 current and proposed operations: Current Proposed Operations Operations Sales $254,900 $254.900 Direct materials $86,800 $86,800 Direct labor 60,300 20,100 Power and maintenance 5,600 9,600 Taxes, insurance, etc. 2,000 6,700 Selling and administrative 60,300 60,300 expenses Total expenses $215,000 $183,500 a. Prepare a differential analysis report for the proposal to replace the machine. Include in the analysis both the net differential change in costs anticipated over the five years and the net annual differential change in costs anticipated. WHITE NOISE TECHNOLOGIES INC.
