A. If a firm operating in a perfectly competitive market doubles the amount it sells, what happens to the price of its output and its total revenue?
B. How does a competitive firm determine its profit-maximizing level of output? When does a competitive firm decide to temporarily shut down in the short run? Explain, using the concepts of marginal cost, marginal revenue, price, and average variable cost.

Suppose the shirts industry is perfectly competitive and begins in a long-run equilibrium.
(a) Pluto Company invents a new production process that reduces the production cost. What happens to Pluto Company’s profits and the price of shirts in the short run when Pluto Company’s patent prevents other firms from using the new technology?
(b) What happens in the long run when the patent expires and other firms are free to use the technology?

- The graph below shows the marginal cost (MC), average variable cost (AVC), and average total cost (ATC) curves for a firm in a competitive market. These curves imply a short-run supply curve that has two distinct parts. One part, not shown, lies along the vertical axis (quantity-0); this represents a condition of production shutdown. Where is the other part? Use the straight-line tool to drawit.
