Clubs The rowing club is renting a 57-passenger bus for a day trip. The cost of the bus is $750. Five passengers will be chaperones. If the students who attend share the bus cost equally, what function models the cost per student C with respect to the number of students n who attend? What is the domain of the function? How many students must ride the bus to make the cost per student no more than $20?

To share the cost equally, divide 750 by the number of students, n, who attend.
The function that models the cost per student is
The bus has a capacity of 57 passengers and there will be 5 chaperones. The maximum number of students is
Is the domain
No; the domain is the possible numbers of students, so only positive integers make sense.
The domain is the integers from 1 to 52.
