A firm produces a product in a competitive industry and has a total cost function C = 80 + 4q + 2q2 and a marginal cost function MC = 4 + 4q. At the given market price of $28, the firm is producing 7 units of output. Is the firm maximizing its profit? What quantity of output should the firm produce in the long run?
A firm produces a product in a competitive industry and has a total cost function (TC) of
TC(q) = 100+8q+2q²
and a marginal cost function (MC) of
MC(q) = 8 +4q.
At the given market price (P) of $18, the firm is producing 2.50 units of output.
Is the firm maximizing profit? Yes
What quantity of output should the firm produce in the long run?
The firm should produce unit(s) of output. (Enter your response as an integer.)
Consider the following cost curve for a firm in a competitive industry where the market price equals $150.
C= =q° + 6q + 1,500.
What is the firm's marginal cost (MC)?
MC = 150. (Properly format your expression using the tools in the palette. Hover over tools to see keyboard shortcuts. E.g., a superscript can be created with the ^ character.)
At what level of output does the firm maximize profits (minimize losses)?
Profit is maximized at 12 units of output. (Round your answer to two decimal places.)
What is the firm's profit maximizing price?
The profit-maximizing price is $ (Round your response to the nearest dollar.)
What is the firm's profit?
The firm earns a profit of $. (Round your response to the nearest penny.)
