a. Construct new demand and supply curves reflecting this change. Describe with words what happened to the supply curve and to the demand curve.
b. Graph the new curves and determine equilibrium price and quantity.
c. Determine equilibrium price and quantity by solving the equations mathematically.
d. Suppose the government set the price of milk at $3 a litre. Demonstrate the effect of this regulation on the market for milk. What is quantity demanded? What is quantity supplied?
