Firm 1 and Firm 2 compete by simultaneously choosing quantity. Both firms sell an identical product in a market with inverse demand {eq}D (Q) = 235 - 3Q {/eq}. Firm i's cost function is {eq}c_i (q_i) = 14 q_i {/eq} and both firms know each other's cost function. They are the only firms supplying this market so {eq}Q = q_1 + q_2. {/eq} Each firm can choose any {eq}q_i \geq 1. {/eq}

a. How many units will each firm produce in equilibrium?

b. What will be the equilibrium price in the market?

c. Suppose the firms were to collude and produce a total quantity that maximises their total profit. That is, the two firms act as a monopolist. What total quantity would they produce?
