(9) Suppose the market for tennis shoes has one dominant firm and five fringe firms. The market demand is Q= 400 – 2P. The dominant firm has a constant marginal cost of 20. The fringe firms each have a marginal cost of MC = 20 + 5q. %3D a. Verify that the total supply curve for the five fringe firms is Q, = P-20. b. Find the dominant firm's demand curve. c. Find the profit-maximizing quantity produced and price charged by the dominant firm, and the quantity produced and price charged by each of the fringe firms.- d. Suppose there are ten fringe firms instead of five. How does this change your results?

1. The cost function for any potential firm in a manufacturing industry is C(y) = 2+ 8y + 2y? (if a firm exits the industry, then its cost is zero). The inverse market demand function is given by P(y) = 100 – 2y. (b) If the industry allows free entry and all the firms are price takers, what is the number of firms in equilibrium?
