Critique the following statement as True or False and explain your reasoning. A profit-maximizing firm will always operate where there revenues exceed their costs.

A profit-maximizing firm decides to shut-down production in the short-run. Its total fixed cost of production is $100, i.e. TFC = $100. Which of the following statements is true?   a If the firm produced, the firm's revenues would have been lower than $100.  bIf the firm produced, the firm's total variable cost must be lower than $100. cIf the firm produced, the firm's losses would have been higher than $100. dIf the firm produced, the firm's total variable cost would have been higher than $100.

draw marginal cost, marginal revenue, and average total cost curves for a typical perfectly competitive firm in long-run equilibrium and indicate the profit maximizing level of output and total profit  for that firm.

A perfectly competitive firm has total revenue and total cost curves given by: TR = 800Q TC = 4,000 + 12Q + 2 Q2 a. Find the profit-maximizing output for this firm. b. What profit does the firm make
