Assume the firm is in the short run and making profits. Draw in the demand and marginal revenue curves. Show output and price. b. Now let the firm reach long-run equilibrium. Draw in precisely the new demand and marginal revenue curves. Show output and price. c. Why must MR = LMC at exactly the same output at which LAC is tangent to demand? d. Contrast this firm's output and price in long-run equilibrium with the price and output if this firm was a perfect competitor
