Question

A class of 24 students is planning a field trip to a science museum. A nonrefundable deposit of $50 is required for the day-long program, plus a charge of $4.50 per student.

Determine a linear function that models the cost, c, and the number of students, s.

Answer 1

This is the linear function: c = 4.5s + 50

This is the cost if all 24 students came along: $158.00

Explanation:

C is the total cost, it is $4.50 per student coming, and there is a $50 non refundable deposit for the program. So, if all 24 students came along for the trip, you would do 24 times $4.50 which is $108 and then add the additional $50 for the nonrefundable deposit, making the total $158.

Answer 2

c = 4.50s + 50

Explanation:

50 is a flat rate so it is a constant. 4.50 is the charge per student so it would be multiplied by the total number of students s.
