Problem 02-03
Suppose the supply function for product X is given by QXS = – 30 + 2Px – 4Pz.

a. How much of product X is produced when Px = \$600 and Pz = \$60?
b. How much of product X is produced when Px = \$80 and Pz = \$60?
c. Suppose Pz = \$60. Determine the supply function and inverse supply function for good X. Graph the inverse supply function.

Supply function:

Inverse supply function:

Problem 02-05 (Algo)
The demand curve for product X is given by QXd = 340 – 4PX.

a. Find the inverse demand curve.
b. How much consumer surplus do consumers receive when Px = \$45?
c. How much consumer surplus do consumers receive when Px = \$30?
d. In general, what happens to the level of consumer surplus as the price of a good falls?

Problem 02-06 (Algo)
Suppose demand and supply are given by Qd = 60 – P and Qs = 1.0P – 20.

a. What are the equilibrium quantity and price in this market?
Equilibrium quantity:
Equilibrium price:

b. Determine the quantity demanded, the quantity supplied, and the magnitude of the surplus if a price floor of \$50 is imposed in this market.

Quantity demanded:

Quantity supplied:

Surplus:

c. Determine the quantity demanded, the quantity supplied, and the magnitude of the shortage if a price ceiling of \$32 is imposed in the market. Also, determine the full economic price paid by consumers.
