AAA Lock Manufacturing Co. makes and sells several models of locks. The cost records for the ZForce lock show that manufacturing costs total $29.00 per lock. An analysis of this amount indicates that $16.75 of the total cost has a variable cost behavior pattern, and the remainder is an allocation of fixed manufacturing overhead. The normal selling price of this model is $38.75 per lock. A chain store has offered to buy 15,000 ZForce locks from AAA Lock at a price of $20.00 each to sell in a market that would not compete with AAA Lock's regular business. AAA Lock has manufacturing capacity available and could make these locks without incurring additional fixed manufacturing overhead.
