Initially, all firms in a perfectly competitive market are in long-run equilibrium. Assume that the market demand for the product produced by the firms
in the market suddenly rises.
Suppose the following graph shows the marginal revenue (MR) and marginal cost (MC) curves of a firm in this market at its initial long-run
equilibrium, with an equilibrium price of P₁ and a profit-maximizing quantity of output of Q₁.
Show the short-run effect of the increase in market demand on this firm by shifting the marginal revenue curve, the marginal cost curve, or both on
the following graph.

If the total cost of 1,000 pencils is $500, the market price per pencil is $2, and the marginal cost is $2, then Peter A) makes an economic profit because marginal revenue is equal to marginal cost at this output level. B) should increase his output to increase his profit. C) is maximizing his profit and is making an economic profit. D) should decrease his output to increase his profit.
