Kindly help me solve this

(1) Consider a product differentiated duopoly market. There are two rms labeled rm A and B. Since the products are imperfect substitutes in the market, the number of units sold depends on the price the rm charges, but also on the price charged by the competitor. Let q, = or pa pb denote the demand curve for rm A and qb = a pg, 3pc, be the demand curve for rm B. Assume a )- 0 and ,5' E (0, 1). Further, let the cost function be C (49,-) = Kq; with K > 0. (a) Given this description, formally dene the game. (b) Solve for the Nash Equilibrium
