22) Doreen's Dairy produces and sells Swiss cheese. Last year, it produced 7,000 pounds and sold each pound for $6. In producing the 7,000 pounds, the dairy incurred variable costs of $28,000 and a total cost of $40,000. Refer to Scenario 13-19. In producing the 7,000 pounds of cheese, the firm's average variable cost was

4.00

26) 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 the firm hires 2 workers, the total cost of production is $100. When the firm hires 3 workers, the total cost of production is $120. In addition, assume that the variable cost per unit of labor is the same regardless of the number of units of labor that are hired. What is the firm's fixed cost?

60

2) Refer to Figure 7-11. If the supply curve is S and the demand curve shifts from D to D', what is the increase in producer surplus due to new producers entering the market?

625

11) Refer to Table 7-16. Both the demand curve and the supply curve are straight lines. At equilibrium, total surplus is

72

U-shaped

39) You purchase a $30, nonrefundable ticket to a play at a local theater. Ten minutes into the show you realize that it is not a very good show and place only a $10 value on seeing the remainder of the show. Alternatively you could leave the theater and go home and watch TV or read a book. You place an $8 value on watching TV and a $12 value on reading a book.

You should go home and read a book
