Suppose that the following graph illustrates the cost curves of a perfectly competitive firm. If the price equals $60, what is the firm’s economic profit?

A consulting company estimated market demand and supply in a perfectly competitive industry and obtained the following results:Qd = 25,000 – 5,000P + 25MQs = 240,000 + 5,000P – 2,000PITC = 6,000 + 14Q – 0.008Q2 + 0.000002Q3where M= $9,000 and PI = $20What is the profit-maximizing output choice for the firm?

Grace owns and operates an ice cream parlor on Clearwater Beach. She is considering whether to stay open during the month of February. If Grace opens her store in February, she will earn total revenue of $4,000 for the month, incurring variable costs of $3,500 and fixed costs of $1,500. Based on this, Grace should:

A consulting company estimated market demand and supply in a perfectly competitive industry and obtained the following results:Qd = 25,000 – 5,000P + 25MQs = 240,000 + 5,000P – 2,000PITC = 6,000 + 14Q – 0.008Q2 + 0.000002Q3where M= $15,000 and PI = $20What will the firm’s profit (loss) be?

Suppose that the following graph illustrates the cost curves of a perfectly competitive firm. If the price equals $10, what is the firm’s maximum profit?

Good Z is produced and sold in a competitive industry, and long-run industry supply is characterized by constant costs. The figure below shows a typical long-run average cost curve (LAC) for each of the firms producing good Z. LAC reaches its minimum unit cost of $12 and 1,000 units of output (point M). Suppose the demand for good Z is Qd = 52,000 – 1,000P.In long-run competitive equilibrium, if demand for good Z decreases, then LMC _________ (falls, rises, stays the same), LAC _________ (falls, rises, stays the same), and economic profit _________ (falls, rises, stays the same).

Radon Research Corporation (RRC) is one of 24 firms in Albuquerque testing homes for dangerous levels of radon gas. There is a standard test that all testing companies use. The manager of RRC wants to know the number of homes to test in 2024 in order to maximize the firm’s profit. The manager forecasted a price of $160 for radon tests in 2024. The firm’s marginal cost was estimated as SMC = 200 – 15Q + 0.8Q2 where Q is the number of tests performed each week. RRC’s fixed cost will be $250 per week. The weekly profit (loss) at RRC in 2024 will be

The table below shows a competitive firm’s short-run production function. Labor is the firm’s only variable input, and market price for the firm’s product is $2 per unit. A table shows the data on units of labor and units of output. Units of Labor Units of Output 3 370 4 490 5 570 6 600 7 620 How much does the fifth unit of labor add to the firm’s total revenue?

Below, the graph on the left shows long-run average and marginal cost for a typical firm in a perfectly competitive industry. The graph on the right shows demand and long-run supply for an increasing-cost industry. How much profit will the firm earn?

The graph above shows cost curves for a perfectly competitive firm. If market price is $5, how much profit will the firm earn?
