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 \$257.00 Total fixed manufacturing \$305,800 Variable nonmanufacturing per unit \$53.00 Total fixed nonmanufacturing \$316,800

KCSB expects to produce and sell 2,400 bicycles per month in the coming year. The bicycles sell for \$650 each.

An outside contractor makes an offer to assemble 700 of KCSB's bicycles per month and ship them directly to KCSB's customers as orders are received from its sales force. It will charge KCSB \$160 per bicycle. KCSB would provide the materials for each bicycle, but the outside contractor would assemble, box, and ship the bicycles. If KCSB accepts the offer, its variable manufacturing costs would be reduced by 35% for the 700 bicycles assembled by the outside contractor, and its variable nonmanufacturing costs for those 700 bicycles would be cut by 55%. In addition, it would be able to save \$15,290 of fixed manufacturing costs; fixed nonmanufacturing costs would be unchanged.

KCSB's marketing manager thinks that it could sell 80 specialty 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 \$450 per bicycle.

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.)

Solution:

 KCSB - Comparative Analysis of monthly cost of accepting and rejecting the proposal of assembling Particulars Alt 1 - Accept assembly propsal Alt 2 - Reject assembly propsal Differential effect (Alt 1) Total assembling charges to be taken by outside contractor (700*\$160) \$1,12,000.00 \$0.00 -\$1,12,000.00 Variable manufacturing cost Alt 1 - 257*65%*700 Alt 2 = 257*700 \$1,16,935.00 \$1,79,900.00 \$62,965.00 Variable nonmanufacturing cost Alt 1 - 53*45%*700 Alt 2 = 53*700 \$16,695.00 \$37,100.00 \$20,405.00 Reduction in Fixed Manufacturing cost -\$15,290.00 \$15,290.00 \$0.00 Contribution from sale of special racing bicycle on acceptance of proposal (\$5,500 - \$4,300 - \$450)*80 -\$60,000.00 \$0.00 \$60,000.00 \$0.00 Net monthly cost of each alternative \$1,70,340.00 \$2,17,000.00 \$46,660.00
