SureLock Manufacturing Co. makes and sells several models of locks. The cost records for the ZForce lock show that manufacturing costs total $23.00 per lock. An analysis of this amount indicates that $13.34 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 $35.00 per lock. A chain store has offered to buy 14,000 ZForce locks from SureLock at a price of $16.10 each to sell in a market that would not compete with SureLock's regular business. SureLock has manufacturing capacity available and could make these locks without incurring additional fixed manufacturing overhead.
