23) 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:
Assume that Vincent's customers are always available for the tour¾ therefore, he can
fill his bus for each tour as long as there is sufficient total demand for the day.
One of Vincent's friends tells him he would be more profitable if he charged a single
price of $12. Assuming no changes in consumer demand, what would Vincent's profit
be if he charged every customer $12?
