A firm is producing 8 units of output at an average total cost of $40. When the firm produces 9 units of output, average total cost rises to $54. What is the marginal cost of the 9th unit of output?

Suppose the supply curve for backpacks is Q = 2P – 36. What is the highest price at which no producer is willing to sell backpacks (i.e., the supply choke price)?

A perfectly competitive firm maximizes profit by producing 500 units of output, selling each unit for $5. The firm’s average variable cost is $2, and its average fixed cost is $1. What is the firm’s profit?

In the market for apartment rentals, the demand and supply equations are given by QD = 5,000 – 3P and QS = 5P + 1,000, where P is the price per apartment and Q measures the quantity of apartments. What is the equilibrium quantity?

Refer to the following figure. C1 , C2{“version”:”1.1″,”math”:”C1 , C2″} and C3{“version”:”1.1″,”math”:”C3″} are isocost curves. Which of the following points minimize the cost of producing Q = Q{“version”:”1.1″,”math”:”Q = Q”} ?

Suppose that the inverse demand in a market is P = 100 – 2Q. A firm’s marginal cost is constant and equal to $50. If the marginal cost increased from $50 to $60 and the firm is a monopoly, then it would raise its price _____. If the marginal cost increased from $50 to $60 and the firm operates in a perfectly competitive market, then the market price would _____.

A firm is producing 4 units of output at an average total cost of $10. When the firm produces 5 units of output, average total cost rises to $20. What is the marginal cost of the fifth unit of output?

In a perfectly competitive industry, the equilibrium price is $10, and the minimum average total cost of the industry’s firms is $20. If this is a constant-cost industry, we can expect that in the long run, firms will _____ the market, shifting the industry’s short-run supply curve _____.

If a firm practices first-degree price discrimination, the firm must

Which of the following is an example of the sunk cost fallacy?
