The chair-making industry currently consists of 90 producers, all of whom operate with the identical short-run total cost curve STC(Q)=500+3Q2, where Q is the annual output of a firm. Only $200 of each firm's fixed cost is sunk. The market demand curve for lamps is D(P)=2880-P, where P is the market price.
