A) Current equilibrium price is $2.50

B) If supply at every price is reduced by 10 gallons, the new equilibrium price would be $3.00

Please note that answers below assume we are using the “new demand” curve as identified in figure 3.7 of the text.

A) At a price of $40 a market surplus of approximately 37 hours per semester would exist.
