The figure below shows the industry demand curve and two possible industry supply curves in the perfectly competitive market for cheeseburgers. 8 Price ($) 7 6 5 3 2 1 0 3 Select one: B 4 5 6 7 8 S₂ 9 10 11 a. an excess supply of 6 cheeseburgers. b. an excess demand of 4 cheeseburgers. C. an excess supply of 3 cheeseburgers. d. an excess demand of 6 cheeseburgers. S₁ D 12 Cheeseburgers The market depicted in the figure above is initially at equilibrium at Point A. Suppose firms begin to exit the market, causing the supply curve to shift from S₁ to S₂. If the price of cheeseburgers remains constant at $5.00, as a result of the decrease in supply there will be Q

7. Notepads and pens can be considered to be complements. Woodchips are an input to notepads, and plastic is an input to pens. Assume markets for notepads, pens, woodchips and plastic, are all perfectly competitive. Suppose that the equilibrium price of notepads increases, and the equilibrium price of pens decrease. Which of the following could explain these changes? a) A decrease in the supply of plastic b) An increase in the demand for wood chips c) An increase in the demand for plastic d) An increase in the supply of plastic e) Either (b) or (d)

A) What is the profit-maximizing price? B) What is the profit-maximizing quantity? C) What is total revenue at the profit-maximizing quantity?

22. Suppose the firm in the figure below sets a uniform price for its product. Please show the steps.  a. If the firm chooses to set a uniform price for its product, then the profit-maximizing price is $________ and ________ units will be sold. Under this uniform pricing policy, the maximum possible profit is $________. b. The maximum profit the firm could earn if the firm sells 2,000 units and is able to charge the demand price for every one of the 2,000 units it sells is $ ________. c. For the additional number of units sold by expanding output to 2,000 units (from the output level in part a), the consumer surplus that could be captured if it were possible to charge the demand price on every one of those units would amount to $________.
