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.

Alternatively, assume now that these firms compete in Bertrand fashion.
