Suppose the market demand curve (D) in an oligopoly market characterized by a dominant firm and a fringe is given by Q = 25 - 2P. The fringe supply curve is given by QF = -1 + 0.3P. If the marginal cost of production for the dominant is $3, calculate the market price and total output produced by the dominant firm and the fringe
