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?
Suppose the market for peaches is perfectly competitive. The short-run average
total cost and marginal cost of growing peaches for an individual grower are
illustrated in the figure to the right.
Assume that the market price for peaches is $28.00 per box. What is
the profit-maximizing quantity for peach growers to produce? boxes. (Enter
your response as an integer.)

Q
The demand curve and supply curve for carpet cleaning in the local market are currently as follows: Demand: Q = 1,000 - 1OP
Supply: Q = 640 + 2P
The total cost function for the typical carpet cleaning company is: TC= 75 + 3q2 (so that FC=75, VC=3q2 and MC= 6q), where costs are measured in dollars and q is output per year. The market is perfectly competitive.
First question how do I calculate the optimal output for the typical carpet cleaning firm in the short run and how many firms would operate in the market in the short run?
Second, how would I compute operating profits and total profits for the typical firm in the short run. Based on the results so far, would you say that this market is at the long-run equilibrium?
