There are two firms in an in an industry. Let q1 and q2 be the two firms in an industry and Q= q1 + q2 be the total output. The inverse demand in the industry if P (Q)= 45 – Q. The cost function for each firm is C(qi) = 9qi.

B. Both of the above are true.

C. Each firm tries to maximize its profit while choosing its price, while taking its rival’s price to be given.

A. 6,18

B. 9, 15

C. 9, 18
