Given a perfectly competitive market structure at the
profit-maximizing output level, a firm’s total fixed cost is $32,
total variable cost is $174, marginal revenue is $6.60, and the
quantity demanded is 38 units. Calculate the firm's profit at the
profit-maximizing output level. Show your work. Show your work.

A competitive firm faces a market price of $15. The firm has a
total cost function equal to TC(q) = 30 + 5q + q2 . What quantity
does the firm produce? What are its profits? Will the firm shut
down in the short run? Explain.
Consider the following cost data for a perfectly competitive
firm:

A perfectly competitive market is characterized by every firm
having the following cost structure: C = 100 + q2. In
long-run equilibrium, what is the market price?

P = $35
A firm in a competitive industry has the following total and
marginal cost functions: ? = ?? + ?? + ?? ?? = ? + ?? Suppose that

should the firm produce in order to maximize profits?
b. Write down the following cost functions for this firm: i.

In a perfectly competitive market structure, a competitive firm
has the given price as a price taker and, therefore, its price is
equal to its MR shown on the same demand curve as the perfectly
elastic demand curve. On the other hand, a monopoly firm has a
downward sloping demand curve and its equilibrium price is always
larger than MR (P>MR). Briefly explain why? Use both equation
and diagram.
A firm operating in a perfectly competitive market has the
following total cost function: TC=0.4Q2+40. Its marginal
cost function is given by: MC=0.8Q. There are 20 identical firms in

given by: Q=300-5P
