Question

Joanne drives a tour bus in Hollywood that can hold up to 10 passengers. She charges each passenger $15 dollars to ride. What is a reasonable domain for this scenario (see graph at right)?

Answer 1

Let p = number of passengers. Because the bus holds at most 10 and you can't have negative or fractional people, the reasonable domain is the integers 0,1,2,...,10. (If shown as an interval for a graph, [0,10], but realistically only whole numbers are allowed.)
