3) The oil drilling industry consists of 60 producers, all of whom have an identical short-run total cost curve, C = 64 + 2612, where q is the monthly output of a firm and $64 is the monthly fixed cost. Assume that $32 of the rm's monthly $64 fixed cost can be avoided if the firm produces zero output in a month. The market demand curve for oil drilling services is D(P) = 400 - 5P, where D(P) is monthly demand at price P. Find the market supply curve in this market, and determine the short-run equilibrium price
