Question

A motel has 50 rooms. The equation m(r) = 125r gives the amount of money made when r people rent the rooms. What is the range for this situation?

Answer 1

Since motel has 50 rooms, then the minimum number of people renting the room is 0 and maximum number is 50.
When r=0, m(0)=0;
When r=50, m(50)=125·50=6250.
The range is [0,6250].
