(a) The price in the market can be taken to be the marginal revenue that each unit generates. The firm will produce a quantity that maximizes the profit for the firm. This can be obtained by using the condition MR = MC. In this case it will mean finding a point where the price is equal to the marginal revenue of $70. The quantity corresponding to that price is 5, and hence the firm will produce 5 units.
