Suppose Sophia sells flowers in a perfectly competitive market and always maximizes profit. (a) Given the current market price is $5, Sophia sells 2000 flowers every week and makes zero profit. What are the amounts of marginal revenue, marginal cost and average total cost at this level of output? Briefly explain. (b) Continued from (a), if the market demand decreases, what will be the short-run impact on Sophia’s profit? Explain in detail with diagrams.

“An upward – sloping demand curve doesn’t make sense in my business. All I know is that if I raise my prices, revenue doesn’t go up, it goes down. I don’t sell more products, I sell less. “Can you straighten out this business man’s thinking?
Would a firm earning zero economic profit continue to produce, even in the long run? In long-run competitive equilibrium, a firm earning zero economic profit A. will not continue to produce because this return is not covering its opportunity costs. B. will not continue to produce because it would be better off shutting down. C. will not continue to produce because such profit corresponds with negative accounting profit. D. will continue to produce because such profit is as high a return as could be earned elsewhere. E. will not continue to produce because it could earn a better return in another industry.
If a profit-maximizing, competitive firm is producing a quantity at which marginal cost is between average variable cost and average total cost, it will A. keep producing in the short run but exit the market in the long run.
