Question is in the attached image. Thank you!

4) Here we are going to work with the Stackelberg leader model and the Cournot model. Suppose that the market demand curve is given by p(y1 + yz) = (10 - (y1 + y2)). Initially, suppose both firms have a marginal cost of 0. Firm 1 will have the marginal revenue function MR1 = 10 -2y1 - y2 and firm 2 has MR2 = 10 - y1 - 2y2 a) Set up the problem for the follower, firm 2, and solve for the reaction function y2(y1). b) Set up the leaders problem for firm 1 and solve for y1, y2, p and the profit of each firm. c) Repeat the exercise assuming that firms choose output simultaneously (This is the Cournot case). d) Explain the difference in outcomes
