Consider the following oligopolistic market. In the first stage, Firm 1 chooses quantity q1 . Firms 2 and 3 observe Firm 1's choice, and then proceed to simultaneously choose q2 and q3, respectively. Market demand is given by p(Q) = 100 - Q, and @ = q1 + q2 + q3. Firm 1's costs are ci (91) = 391, firm 2's costs are c2(q2) = 4q2 and firm 3's costs are C3(93) = 493- Starting from the end of the game, you can express Firm 2's best response function in terms of q, and q3, and you can similarly express Firm 3's best response function in terms of q, and 92. Using these, answer the following questions
