a. Suppose the firm sells its output for $9.10. What is the firm's marginal revenue (MR)? Explain.
b. Compare MR to marginal cost (MC) to determine the firm's profit maximizing (loss-minimizing) output level. Be sure to check whether or not the firm should shut down. Show all work & explain your answers well.
c. What is the firm's per-unit profit (loss) and total profit (loss) at this output level? Show all your work.
d. Repeat parts a. through c. assuming the price has fallen to $7.10.
e. Repeat again assuming the price has fallen to $6.10.
f. At what price does the firm earn a normal profit? Explain.
g. At what price must this firm shut down? Explain.

c. What is the equilibrium quantity in this market?
d. What is the equilibrium price in this market?
e. What are the resulting output, revenue, cost, and profit of the typical firm?
4. Indicate whether each of the following statements is true or false, and explain why. If a statement is false or true, do not simply give a corrected statement -- you must provide a full explanation as to why that statement is correct or not.
a. Consumer surplus is the difference between the minimum and maximum price a consumer is wiling to pay for a good.
b. Producer surplus is the difference between the actual price a producer receives for a product and the minimum price the producer would have been willing to accept for the product.
c. For Good A, supply elasticity is +2.5 and price elasticity of demand is -1.5. If an excise tax is imposed on Good A, sellers will pay the more of this tax than buyers.
d. A perfectly competitive firm can maximize its economic profit or minimize its losses only by adjusting its output.
e. If a perfectly competitive firm is producing output less than its profit-maximizing output, marginal revenue is greater than marginal cost.
5. Suppose at present firms in a perfectly competitive market are earning negative economic profits (losses). Explain the process by which this industry will reach long-run equilibrium. What will happen to the output produced by the average firm and the prices charged? Why? What will happen to profit? Some graphs to illustrate your answers may be very useful
