Question

Make sure you understand the two alternatives. The "make" means that KCSB makes, assembles, and ships all of its bicycles. The "buy" means that KCSB

makes, assembles, and ships some of its bicycles,

makes some of its bicycles and pays another firm to assemble and ship them, and

uses idle resources to make and sell specialty racing bicycles

______________________________________________________

King City Specialty Bikes (KCSB) produces high-end bicycles. Costs to manufacture and market the bicycles at last year's volume level of 2,050 bicycles per month are shown in the following table:

Variable manufacturing per unit	$258.00
Total fixed manufacturing	$272,650
Variable nonmanufacturing per unit	$59.00
Total fixed nonmanufacturing	$282,900

KCSB expects to produce and sell 2,250 bicycles per month in the coming year. The bicycles sell for $650 each.

KCSB receives a proposal from an outside contractor who, for $155 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 35% 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 70 specialty racing bicycles per month for $6,500 each, and its production manager thinks that it could use the idle resources to produce each of these bicycles for variable manufacturing costs of $5,500 per bicycle and variable nonmanufacturing costs of $450 per bicycle.

If KCSB accepts the proposal, it would be able to save 10% of fixed manufacturing costs; fixed nonmanufacturing 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.)

answer: _________

Answer 1

Solution:

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 (800*$155)	$124,000.00	$0.00	-$124,000.00
Variable manufacturing cost Alt 1 - 258*65%*800 Alt 2 = 258*800	$134,160.00	$206,400.00	$72,240.00
Variable nonmanufacturing cost Alt 1 - 59*40%*800 Alt 2 = 59*800	$18,880.00	$47,200.00	$28,320.00
Reduction in Fixed Manufacturing cost ($272650*10%)	-$27,265.00		$27,265.00
			$0.00
Contribution from sale of special racing bicycle on acceptance of proposal ($6,500 - $5,500 - $450)*70	-$38,500.00	$0.00	$38,500.00
			$0.00
Net monthly cost of each alternative	$211,275.00	$253,600.00	$42,325.00

Hence difference in KCSB's monthly costs between accepting the proposal and rejecting the proposal si $42,325
