A video rental store charges a $20 membership fee and $2.50 for each video rented. Step # 1 - Write a linear equation (y=mx+b) to model this situation.

Step #2 - If a new member paid the store $67.50, how many videos were rented?

Respuesta :

1. Y = Mx + B

Y = ?
mx = 2.50x
B = 20

Y = 2.50x + 20


2. 67.50 - 20 = 47.50
47.50 / 2.50 = 19
19 videos were rented
