Question

A youth group is planning a trip to a theme park. The bus holds up to 40 people. The cost for bus parking is $60.00. Each person going on the trip will be paying $36.00 for a ticket to enter the park. The equation that models this trip is T = 36x + 60, where T represents the total cost for the group to take the trip and x equals the number of people going. What values are appropriate for the domain? A. X=40 B. X=60 C. 0<_X<_40 D. 0<_X<_39

Answer 1

C. 0 ≤ X ≤ 40

Explanation:

The equation is valid for positive values of x not greater than 40.

_____

Personally, I might put the domain at 1 ≤ x ≤ 40, because there's no point in using the equation (or parking the bus) if zero people are going on the trip.
