The original cost of the machine is $84,000, the accumulated depreciation is $33,600, its remaining useful life is 5 years, and its residual value is negligible. On October 1 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 $174,700. The automatic machine has an estimated useful life of 5 years and no significant residual value. For use in evaluating the proposal, the managerial accountant accumulated the following annual data on present and proposed operations: Sales Direct materials Direct labor Power and maintenance Taxes, insurance, etc. Selling and administrative expenses Total expenses Present Proposed Operations Operations $266,300 $266,300 $90,700 $90,700 63,000 5,900 31,100 2,100 7,000 63,000 63,000 $224,700 $191,800 a. Prepare a differential analysis dated October 1 to determine whether to continue with (Alternative 1) or replace (Alternative 2) the old machine. 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. Differential Analysis Continue with (Alt. 1) or Replace (Alt. 2) Old Machine Line Item Description Revenues: October 1 Continue with Old Machine (Alternative 1) Replace Old Machine Differential Effects (Alternative 2) (Alternative 2) Sales (5 years) Costs: Purchase price Direct materials (5 years) Direct labor (5 years) Power and maintenance (5 years) Taxes, insurance, etc. (5 years) Selling and admin. expenses (5 years) Profit (loss) 174,700 -174,700 0
