King City Specialty Bikes (KCSB) produces high-end bicycles. Costs to manufacture and market the bicycles at last year's volume level of 2,200 bicycles per month are shown in the following table Variable manufacturing per unit Total fixed manufacturing Variable nonmanufacturing per unit Total fixed nonmanufacturing $230.00 $283,800 $56.00 $312,400 KCSB expects to produce and sell 2,550 bicycles per month in the coming year. The bicycles sell for $590 each KCSB receives a proposal from an outside contractor who, for $170 per bicycle, will assemble 800 bicycles per month and ship them directly to KCSB's customers as orders are received from KCSB's sales force. KCSB would provide the materials for each bicycle, but the outside contractor would assemble, box, and ship the bicycles. The variable manufacturing costs would be reduced by 40% for the 800 bicycles assembled by the outside contractor, and variable nonmanufacturing costs for the 800 bicycles would be cut by 60%. KCSB's marketing manager thinks that it could sell 85 speclalty racing bicycles per month for $5,500 each, and its production manager thinks that it could use the idle resources to produce each of these bicycles for variable manufacturing costs of $4,300 per bicycle and variable nonmanufacturing costs of $400 per bicycle. If KCSB accepts the proposal, it would be able to save 14,190 of fixed manufacturing costs, fixed non manufacturing costs would be unchanged REQUIRED [Note: Round unit cost computations to the nearest cent] What is the difference in KCSB's monthly costs between accepting the proposal and rejecting the proposal? (Note: If the costs of accepting the proposal are less than the costs of rejecting it, enter the difference as a positive number; if the accept costs are more than the reject costs, enter the difference as a negative number.) ncorrect
