11) Jerry consumes two goods, hamburgers and ice cream sandwiches. He has
maximized his utility given his income. Ice cream sandwiches costs $2, and he
consumes them to the point where the marginal utility he receives is 6. Hamburgers cost
$4, and the relationship between the marginal utility that Jerry gets from eating
hamburgers and the number he eats per month is as follows:
How many hamburgers does Jerry buy each month?
a.1
b.2
c.3
d.4
12) In order to explain the changing gap in earnings between skilled and unskilled

c.the decreasing importance of labor unions.

13) Answer the following questions based on the graph that represents J.R.’s demand for
ribs per week at Judy’s Rib Shack.
a.At the equilibrium price, how many ribs would J.R. be willing to purchase?
b.How much is J.R. willing to pay for 20 ribs?
c.What is the magnitude of J.R.’s consumer surplus at the equilibrium price?
d.At the equilibrium price, how many ribs would Judy be willing to sell?
e.How high must the price of ribs be for Judy to supply 20 ribs to the market?
f.At the equilibrium price, what is the magnitude of total surplus in the market?
g.If the price of ribs rose to $10, what would happen to J.R.’s consumer surplus?
h.If the price of ribs fell to $5, what would happen to Judy’s producer surplus?
i.Explain why the graph that is shown verifies the fact that the market equilibrium
(quantity) maximizes the sum of producer and consumer surplus.
