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 is the firm’s minimum average variable cost?

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

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

Good W is produced in a competitive industry with increasing costs of production. The figure below shows how a typical firm’s long-run average cost curve shifts upward as industry output of good W expands. With 50 firms in the industry, each firm faces an identical long-run average cost curve given by LAC. With 80 firms in the industry, each firm faces an identical long-run average cost curve given by LAC’. And with 120 firms in the industry, each firm faces an identical long-run average cost curve given by LAC”. When there are 80 firms in the industry in long-run competitive equilibrium, the long-run average cost (LAC) of producing good W is $_________, and each firm earns $_________ of 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= $10,000 and PI = $20What is the profit-maximizing output choice for the firm?

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?

A competitive firm will maximize profit by producing the level of output at which
