King City Specialty Bikes (KCSB) produces high-end bicycles. The costs to manufacture and market the bicycles at the company's volume of 2,000 units per month are shown in the following table:

a. KCSB receives a proposal from an outside contractor who will assemble 800 of the2,000 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 percent for the 800 bicycles assembled by the outside contractor. KCSB's fixed nonmanufacturing costs would be unaffected, but its variable nonmanufacturing costs would be cut by 60 percent for these 800 units produced by the outside contractor. KCSB's plant would operate at 60 percent of its normal level, and total fixed manufacturing costs would be cut by 25 percent.

a-1. Calculate the in-house cost that must be compared with the quotation received from the outside contractor.

a-2. Should the proposal be accepted for a price of $160 per unit?

b. Assume the same facts as in requirement (a) but assume that the idle facilities would be used to produce 80 specialty racing bicycles per month. These racing bicycles could be sold for $8,700 each, while the costs of production would be $6,300 per unit variable manufacturing expense.

Variable marketing cost would be $270 per unit. Fixed nonmanufacturing and manufacturing costs would be unchanged whether the original 2,000 regular bicycles were manufactured or the mix of 1,200 regular bicycles plus 80 racing bicycles was produced. What is the total net profit/loss for the following.

b-1. When the company produces and sells 2,000 units of regular bicycles per month.

b-2. When the company produces 1,200 units of regular bicycles and use the idle facilities to produce 80 specially racing bicycles per month.
