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.

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? Determine consumer surplus with the price floor.
