Consider a Cournot oligopoly with two firms, where the demand curves are given by P = 150-Q- 20 P =150-20 -22 and that costs are given by TC ( @ , ) = -Q-, . , MC = Q, TC(9,) - 10 Q4, and MC = 2, Also, marginal revenues can be written as MR. = 150-20, - 20, MR = 150-20 - 20 . Solve for each firm's best response function
