If the firm continues to produce and sell its goods, then which of the following must be true?The firm is covering all of its fixed and variable costs of production.The firm is covering all of its fixed costs but not all of its variable costs of production.The firm must have raised the price of its goods in order to minimize its losses.The firm is covering all of its variable costs but not all of its fixed costs of production.
- 3. Multiple ChoiceBased on the cost and output data in the table shown, a perfectly competitive firm will shut down if price falls below:$15$16$18$20
- 4. Multiple ChoiceFor a perfectly competitive firm producing the profit-maximizing quantity, the average total cost is $10 and the average variable cost is $8. If the market price for its product is $10, which of the following is true for the firm?It is sustaining a loss and should shut down.It is earning zero economic profit and will remain in business.
It will temporarily shut down until price rises.The firm is earning positive economic profit. - 5. Multiple ChoiceA profit-maximizing firm will shut down in the short run any time the firm’s total revenue is less than its:total cost

- 6. Multiple ChoiceSuppose that price in a perfectly competitive industry decreases and it is now below minimum average total cost but remains above minimum average variable cost. Which of the following will occur in the short run?Firms will increase output so that marginal revenue equals the new price.

- 7. Multiple ChoiceIn the graph pictured, TC is total cost and TR is total revenue. At what quantity is profit maximized?Q1Q2Q3Q4
- 8. Multiple ChoiceIn the short run, a profit-maximizing firm, faced with U-shaped average cost curves, is producing a level of output at which the average total cost of production is minimized. At this level of output, which of the following is true for the firm?Marginal cost equals average total cost.Marginal cost equals average variable cost.Marginal cost equals average fixed cost.Profit per unit equals marginal cost.
- 9. Multiple ChoiceIn the short run, if a firm produces the level of output at which marginal revenue is equal to marginal cost but price is less than average total cost, the firm will:always shut down production
expand output to lower its average fixed costcontinue to operate if price is greater than its average variable cost
