The market demand curve is P = 90 − 2Q, and each firm’s total
cost function is C = 100 + 2q2.
1. Suppose there is only one firm in the market. Find the market
price, quantity, and the firm’s profit.
2.Show the equilibrium on a diagram, depicting the demand
function D (with the vertical and horizontal intercepts), the
marginal revenue function MR, and the marginal cost function MC. On
the same diagram, mark the optimal price P, the quantity...
