Always Round Tire is the only producer of tires for the new British import, the Maxi Copper. Demand for a set of four tires is P = 800 - 5Q (note: Marginal Revenue has twice the slope as the demand curve) while the cost incurred by the firm is MC = 15Q. What would be the monopoly price quantity? What would happen to price and quantity if the market was perfectly competitive (assuming the same costs)?
