In the long run, a monopolistically-competitive firm sells at a price that is A. equal to average total cost, but higher than marginal cost. B. equal to marginal cost and marginal revenue. C. equal to average total cost, but lower than price. D. equal to the value of the demand curve at QMAX, but higher than average total cost and marginal cost.

3. A monopolistically competitive firm sells boots and has the following in the short run: Demand: P = 80 – 0.5Q %3D MR: MR = 80 – Q TC = 1.5Q? + 40 1.5Q + (40/Q) TC: АТC: MC: MC = 3Q %3D Find the firm's profit maximizing quantity and price. Find the firm's profit or loss. Show some work here: Quantity = Price = Profit or Loss = (circle one, and write the number)
