Suppose the price of a bag of frozen chicken nuggets decreases from $6.50 to $5.75 and, as a result, the quantity of bags demanded increases from 600 to 800. Using the midpoint method, the price elasticity of demand for frozen chicken nuggets in the given price range is

2.33

Why doesn't the total cost curve begin at the origin (the point 0,0)?

Because fixed costs are positive when output is zero

If the firm is currently producing 14 units, what would you advise the owners?

Suppose that a firm in a competitive market faces the following revenues and costs: In order to maximize profits, the firm will produce

5 units of output because marginal revenue equals marginal cost

If the demand curve is D and the supply curve shifts from S' to S, what is the change in producer surplus?

Producer surplus increases by $1,875

A firm produces 400 units of output at a total cost of $1,200. If total variable costs are $1,000,

average fixed cost is 50 cents

A government-imposed price of $24 in this market is an example of a

binding price floor that creates a surplus

For each of the three potential buyers of oranges, the table displays the willingness to pay for the first three oranges of the day. Assume Allison, Bob, and Charisse are the only three buyers of oranges, and only three oranges can be supplied per day.

decreases by $0.95.

Goods with many close substitutes tend to have

more elastic demands

Suppose a firm in a competitive market reduces its output by 20 percent. As a result, the price of its output is likely to

remain unchanged

Cost is a measure of the

seller's willingness to sell

Suppose that in a particular market, the supply curve is highly elastic and the demand curve is highly inelastic. If a tax is imposed in this market, then the

buyers will bear a greater burden of the tax than the sellers

When firms are said to be price takers, it implies that if a firm raises its price,

buyers will go elsewhere.

Billy's Bean Bag Emporium produced 300 bean bag chairs but sold only 275 of the units it produced. The average cost of production for each unit of output produced was $100. The price for each of the 275 units sold was $95. Total profit for Billy's Bean Bag Emporium would be

Suppose that for a particular firm the only variable input into the production process is labor and that output equals zero when no workers are hired. In addition, suppose that the average total cost when 5 units of output are produced is $30, and the marginal cost of the sixth unit of output is $60. What is the average total cost when six units are produced?

$35

Suppose that for a particular firm the only variable input into the production process is labor and that output equals zero when no workers are hired. In addition, suppose that when four units of output are produced, the total cost is $175, and the average variable cost is $33.75. What would the average fixed cost be if ten units were produced?

Jacqui decides to open her own business and earns $50,000 in accounting profit the first year. When deciding to open her own business, she withdrew $20,000 from her savings, which earned 5 percent interest.

Allen tutors in his spare time for extra income. Buyers of his service are willing to pay $40 per hour for as many hours Allen is willing to tutor. On a particular day, he is willing to tutor the first hour for $10, the second hour for $18, the third hour for $28, and the fourth hour for $40. Assume Allen is rational in deciding how many hours to tutor. His producer surplus is
