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?
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.)

Assume that a firm in a competitive market faces the following cost information. If the market price for this firm's product is $40, calculate the profit maximizing level of output for this firm using marginal analysis. It may help to create your own cost table and fill in columns for Marginal Cost and Average Total Cost based on the Total Cost information below.
a.What is the level of profit for this firm at the profit maximizing output?
b.To convince yourself that the quantity you found is indeed the profit maximizing quantity, try calculating what the profit would be at the next higher level of output. What did you find?
c. What do you predict will happen in this market over the long run?
