Suppose there are two firms in a market who each simultaneously choose a quantity. Firm 1's quantity is q1, and firm 2's quantity is q2. Therefore the market quantity is Q = q1+ q2. The market demand curve is given by P = 100 - 4Q. Also, each firm has constant marginal cost equal to 28. There are no fixed costs.

The marginal revenue of the two firms are given by:

MR1= 100 - 8q1- 4q2

MR2= 100 - 4q1- 8q2
