WindAirs division manager believes sales can be increased if the unit selling price of the air conditioners is reduced. A market research study conducted by an independent firm indicates that a 5% reduction in the selling price ($20) will increase sales volume by 16%, or 2,400 units. WindAir has sufficient production capacity to manage this increased volume with no increase in fixed costs.

WindAir currently uses a compressor in its units that it purchases from an outside supplier at a cost of $70 per compressor. The division manager of WindAir has approached the manager of the Compressor Division regarding the sale of a compressor unit to WindAir. The Compressor Division currently manufactures and sells a unit exclusively to outside firms that is similar to the unit used by WindAir. The specifications of the WindAir compressor are slightly different, which will reduce the Compressor Divisions materials costs by $1.50 per unit. In addition, the Compressor Division will not incur any variable selling costs for the units sold to WindAir. The manager of WindAir wants all of the compressors it uses to come from one supplier and has offered to pay $50 for each compressor unit.

The Compressor Division has the capacity to produce 75,000 units. The coming years budgeted income statement for the Compressor Division is shown below and is based upon a sales volume of 64,000 units without considering WindAirs proposal.
