Problem 2: Would a change in the price of milk likely cause a change in the demand for yogurt, a complement? Explain why.
Problem 3: If the demand and supply curve for dish washers are:
D= 200 - 4P, S= 32 +12P
Where P is the price of dish washers, what is the quantity of dish washers bought and sold at equilibrium?
