In a competitive market the current price is $5. The typical firm in the market has ATC = $5.50 and AVC = $4.50.
In the short run firms will continue to operate, but in the long run firms will leave the market.
Jose's restaurant operates in a perfectly competitive market. At the point where marginal cost equals marginal revenue, ATC = $20, AVC = $15, and the price per unit is $10. In this situation,

Which of the following is not a characteristic of a perfectly competitive market?
Many firms have market power.

When new firms have an incentive to enter a competitive market, their entry will

Mrs. Smith operates a business in a competitive market. The current market price is $8.10. At her profit-maximizing level of production, the average variable cost is $8.00, and the average total cost is $8.25. Mrs. Smith should

Profit-maximizing firms in a competitive market produce an output level where
marginal cost equals marginal revenue.
When buyers in a competitive market take the selling price as given, they are said to be
