equilibrium. Next, create a table showing the change in quantity demanded or quantity supplied, and a

graph of the new equilibrium, in each of the following situations:

a. The price of milk, a key input for cheese production, rises, so that the supply decreases by 80 pounds

at every price.

b. A new study says that eating cheese is good for your health, so that demand increases by 20% at every

price.

56. Table 3.10 shows the supply and demand for movie tickets in a city. Graph demand and supply and

identify the equilibrium. Then calculate in a table and graph the effect of the following two changes.

a. Three new nightclubs open. They offer decent bands and have no cover charge, but make their money

by selling food and drink. As a result, demand for movie tickets falls by six units at every price.
