Answer: y = 3x + 60

<u>Step-by-step explanation:</u>

Set up two equations and solve the system:

270 = 70x + b

- <u>(150 = 30x + b)</u>

120 = 40x

3 = x

Input "x" into one of the equations and solve for "b":

150 = 30x + b

150 = 30(3) + b

150 = 90 + b

60 = b

Equation: y = 3x + 60

This means that there is a flat fee of $60 plus a rate of $3 per student
