Scenario 15-11
Vincent operates a scenic tour business in Boston. He has one bus which can fit 50 people per
tour and each tour lasts 2 hours. His total cost of operating one tour is fixed at $450. Vincent’s
cost is not reduced if he runs a tour with a partially full bus. While his cost is the same for all
tours, Vincent charges each passenger his/her willingness to pay: adults $18 per trip, children $10
per trip, and senior citizens $12 per trip. At those rates, on a typical day Vincent’s demand is:
Passenger Type
Willingness to Pay
Demand per day
Adults
$18
70
Children
$10
