Graphically show & explain how building more freeways may eliminate the shortage under question 1. (Hint: Supply side management).

question 1 was: The price to drive on a freeway is $0 or free at all times of the day. This price establishes equilibrium at 3 a.m. but it is too low to establish equilibrium at 5 p.m during rush hour. Therefore, there is a shortage of freeway space at 5 p.m. Graphically show & explain how carpooling may eliminate the shortage. (Hint: Demand side management)
