Just Bikes, Inc., sells tricycles, in partially-assembled and fully assembled forms. Parents who assemble their own tricycles benefit from the lower price of $40 per tricycle. "Full-service" customers enjoy the luxury of an assembled tricycle, but pay a higher price of $60 per tricycle. Both partially and fully assembled tricycle prices are stable. The company has observed the following relation between the number of assembly workers employed per day and assembled tricycle output:
