Scenario 16-2 Vincent operates a scenic tour business in Boston. He has one bus that 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 their 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 (Dollars per unit) Quantity Demanded (Units) Adult 18 70 Children 10 25 Senior Citizens 12 55 ​ Assume that Vincent’s customers are always available for the tour; therefore, he can fill his bus for each tour as long as there is sufficient total demand for the day. ​ ​Refer to Scenario 16-2. What is Vincent’s total revenue on a typical day?
