Q: Which formula correctly calculates profit for a firm?

$$\text{Profit} = \text{Total Revenue} - \text{Total Cost}$$

Question 1

In a perfectly competitive market, at what point does a firm maximize its profit?

Accepted Answer

Where marginal cost equals marginal revenue ($$MC = MR)$$

Question 2

A perfectly competitive firm should stop producing additional units when:

Accepted Answer

Marginal cost exceeds marginal revenue ($$MC \u003e MR)$$

Question 3

Which of the following best describes a perfectly competitive market?

Accepted Answer

Firms are price takers and sell identical products

Question 4

If the market price is $$10$$, the marginal cost ($$MC) is$$ $$10$$, and the average total cost ($$ATC) is$$ $$8$$, what is the economic profit per unit?

Accepted Answer

$$2$$

Question 5

Which formula correctly calculates profit for a firm?

Accepted Answer

$$	ext{Profit} = 	ext{Total Revenue} - 	ext{Total Cost}$$

Question 6

A cotton farmer produces at a point where $$P \u003e ATC. $$What does this indicate about the farmer's profitability?

Accepted Answer

The farmer is making an economic profit

Question 7

If a perfectly competitive firm faces a market price below its average variable cost ($$P \u003c AVC$$), what should the firm do in the short run?

Accepted Answer

Shut down production immediately

Question 8

Which of the following is considered economic profit on a cost curve graph?

Accepted Answer

The area between price and average total cost, multiplied by quantity

Question 9

Suppose a firm in perfect competition is producing where $$MR = MC$$ but $$P \u003c ATC. $$What is the firm's economic situation?

Accepted Answer

The firm is making a loss but should continue to produce in the short run

Question 10

How do you determine the quantity at which a perfectly competitive firm maximizes profit?

Accepted Answer

Find where marginal cost equals marginal revenue ($$MC = MR)$$

Question 11

If a firm’s total revenue is $$5000$$ and its total cost is $$4000$$, what is its profit?

Accepted Answer

$$1000$$

Question 12

Which of the following is NOT a characteristic of a perfectly competitive market?

Accepted Answer

Products are differentiated

Question 13

A firm’s marginal cost curve above the average variable cost curve represents:

Accepted Answer

The firm’s short-run supply curve

Question 14

If a firm is producing at a quantity where $$MC \u003c MR$$, what should the firm do to maximize profit?

Accepted Answer

Increase output

Question 15

Which equation represents the break-even point for a perfectly competitive firm?

Accepted Answer

$$P = ATC$$

Question 16

A firm in perfect competition is producing at $$Q^*$$ where $$P = MC = ATC. $$What is the firm’s profit?

Accepted Answer

Zero (normal profit)

Question 17

If a firm’s average variable cost is $$5$$, average total cost is $$8$$, and price is $$7$$, what should the firm do in the short run?

Accepted Answer

Continue producing, even though it is making a loss

Question 18

Which of the following best explains why firms in perfect competition are price takers?

Accepted Answer

Each firm’s output is small relative to the market and products are identical

Question 19

If a firm’s marginal cost is always below its average total cost, what happens to average total cost as output increases?

Accepted Answer

Average total cost decreases

Question 20

Which of the following is the correct shutdown rule for a perfectly competitive firm in the short run?

Accepted Answer

Shut down if $$P \u003c AVC$$
