Ridgeway Digital Components Company assembles circuit boards by using a manually operated machine to insert electronic components. The original cost of the machine is $81,600, the accumulated depreciation is $32,600, 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 $169,700. 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:

Line Item Description	Present Operations	Proposed Operations
Sales	$258,700	$258,700
Direct materials	$88,100	$88,100
Direct labor	61,200
Power and maintenance	5,700	30,200
Taxes, insurance, etc.	2,000	6,800
Selling and administrative expenses	61,200	61,200
Total expenses	$218,200	$186,300

Question Content Area

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.
