A firm producing good Y recently increased monthly production from​ 1,500 units to​ 2,000 units. This had no impact on the market price of good Y. At the new production level of​ 2,000 units, the​firm's average cost is​ $3.5 while its marginal cost of production is​ $4. The marginal revenue however is fixed at​ $5 for all levels of output. Jake Williamson is the operations head of the firm. Jake feels​ that, since the firm has the​ capacity, it should have increased production further to​ 2,500 units which would have maximized profits. On the other​ hand, Mathew Hayden of the market research team anticipates an increase in price to​ $5.5 in the near future. He therefore claims that the firm may not be maximizing economic profit in the short run even at​ 2,500 units.
Which of the following is most strongly implied by this​information?
A. At the current level of​ production, the firm is making a profit of​ $3,000.
B. The current price of good Y is equal to​ $4.
C. Mathew feels that the demand curve faced by the firm will shift downward.
D. Jake thinks that at the production level of​ 2,500 units, the average cost of producing Y will be equal to the market price.
E. The demand curve currently faced by the firm is horizontal at​$4.
