Suppose that each firm in a competitive industry has the following costs: Total cost: TC = 50 + q2 Marginal cost: MC = q where q is an individual firms quantity produced. The market demand curve for this product is Demand:QD = 120 P where P is the price and Q is the total quantity of the good. Currently, there are 9 firms in the market. a. What is each firms fixed cost? What is its variable cost? Give the equation for average total cost. b. Graph average-total-cost curve and the marginal-cost curve for q from 5 to 15. At what quantity is average-total-cost curve at its minimum? What is marginal cost and average total cost at that quantity? c Give the equation for each firms supply curve. d. Give the equation for the market supply curve for the short run in which the number of firms is fixed. e. What is the equilibrium price and quantity for this market in the short run? f. In this equilibrium, how much does each firm produce? Calculate each firms profit or loss. Is there incentive for firms to enter or exit? g. In the long run with free entry and exit, what is the equilibrium price and quantity in this market? h. In this long-run equilibrium, how much does each firm produce?

1. The Abner Corporation, a retail seller of television sets, wants to determine how many television sets it must sell in order to earn a profit of $10,000 per month. The price of each television set is $300, the average variable cost is $100, and the fixed costs are $5,000 per month. a. What is the required sales volume for Abner Corporation to earn a profit of $10,000 per month? b. If the corporation were to sell each television set at $350 rather than $300, what would be the required sales volume? c. If the price is $350 but the average variable cost decreased to $85 rather than $100, what would be the required sales volume now?

Assume hat when the price is exactly equal to the average variable cost, the firm is indifferent between producing zero shirts and the profit-maximizing uantity. Also, indicate whether the firm will produce, shut down, or be indifferent between the two in the short run. Lastly, determine whether it will nake a profit, suffer a loss, or break even at each price. Price Quantity (Dollars per shirt) (Shirts) Profit or Loss? Produce or Shut Down?

(b) You are the CEO for a lightweight compasses manufacturer. The demand function for the lightweight compasses is given by p = 40 – 4q²where q is the number of lightweight compasses produced in millions. It costs the company $15 to make a lightweight compass. (i) Write an equation giving profit as a function of the number of lightweight compasses produced. (ii) At the moment the company produces 2 million lightweight compasses and makes a profit of $18,000,000, but you would like to reduce production. What smaller number of lightweight compasses could the company produce to yield the same profit? Problem з
2. Smile Bright toothpaste company has determined that the demand for its product depends on advertising expenditures A (in thousands of dollars) and the price charged P (in dollars) according to Q = 32A12 - 64P, where Q is the number of tubes of toothpaste sold. The company's marginal costs of production are constant and equal to 50 cents per tube. A. What levels of output, advertising expenditures, and price will maximize the firm's profits? B. Verify at the solution you have found in part A that the marginal revenue from advertising equals the price elasticity of demand.
