Question

10. A video rental store charges a $20 membership fee and $2.50 for each video

rented. Write and graph a linear equation (y=mx+b) to model this situation. If 15
videos are rented, what is the revenue? If a new member paid the store $67.50 in the
last 3 months, how many videos were rented?

Answer 1

Y= 2.50(x) + $20 is the linear equation

If 15 videos are rented
Y=2.50(15) + $20
Y= $57.50

67.50 = 2.50(x) + 20
19= x
19 videos were rented in 3 months
