Consider a single country and a single good. The demand curve for this good is given by QD = 144 - 4P. There
are two firms serving the market: Firm A and Firm B, where Firm A has a marginal cost of $20 and Firm B has
a marginal cost of $16. There are no fixed costs incurred by either firm.

Firm A produces 16 units and firm B produces 32 units.

The equilibrium price is $24.

Total Profit for Firm A = $64

Total Profit for Firm B = $256

Assume that these firms compete in Cournot fashion.
