The wheat market is perfectly competitive, and the market supply and demand curves are given by the following equations: QD = 20,000,000 - 4,000,000P QS = 7,000,000 + 2,500,000P, where QD and QS are quantity demanded and quantity supplied measured in bushels, and P = price per bushel. a. Determine consumer surplus at the equilibrium price and quantity. Provide a fully labelled diagram to support your answer. Show all intercepts, equilibrium points, label axis and curves fully. b. Assume that the government has imposed a price floor at $2.25 per bushel and agrees to buy any resulting excess supply. How many bushels of wheat will the government be forced to buy? Calculate the consumer surplus with the price floor.

The wheat market is perfectly competitive, and the market supply and demand curves are given
by the following equations:
QD = 20,000,000 - 4,000,000P
QS = 7,000,000 + 2,500,000P,
where QD and QS are quantity demanded and quantity supplied measured in bushels, and P =
price per bushel.
a. Determine consumer surplus at the equilibrium price and quantity. Provide a fully
labelled diagram to support your answer. Show all intercepts, equilibrium points, label axis
and curves fully.
b. Assume that the government has imposed a price floor at $2.25 per bushel and agrees to
buy any resulting excess supply.
How many bushels of wheat will the government be forced to buy?
Calculate the consumer surplus with the price floor.
