1. A tennis camp charges $40 per student for a full-day camp. The camp runs only if at least 5 students sign up, and it limits the enrollment to 16 campers a day. The amount of revenue, in dollars, that the tennis camp collects is a function of the number of students that enroll.

The equation R(n) = 40n defines this function.

What is the domain of the function?

• all positive integers less than or equal to 16

• all integers

• all positive integers

• all positive integers greater than or equal to 5 and less than or equal to 16.
