A recent study found that the demand and supply schedules for Frisbees are as shown in the chart at the following link:

What are the equilibrium price and quantity of Frisbees?

Frisbee manufacturers persuade the government that Frisbee production improves scientists' understanding of aerodynamics and thus is important for national security. A concerned Congress votes to impose a price floor $2 above the equilibrium price. What is the new market price? How many Frisbees are sold?

Irate college students march on Washington and demand a reduction in the price of Frisbees. An even more concerned Congress votes to repeal the price floor and impose a price ceiling of $1 below the former price floor. What is the new market price? How many Frisbees are sold?
