Check for Updates Consider a monopolist that produces coal for energy, with demand curve defined by P = 190 – 20 and marginal cost given by MC = 10 + 2Q. Also, the firm's average total cost is ATC = 100/Q + Q+ 10. (Price and costs are in dollars per tonne of coal, while quantity is in thousands of tonnes.) Calculate the monopolisť's profit-maximizing quantity, price, and profit. For a monopoly, profit maximization occurs where the marginal revenue equals the marginal cost. a. b.
