Question

1. A DVD store charges $4.70 for each day, d, a DVD is rented. The store also gives you a dollar off if the DVD is returned before 5 days.

a. Write a rule to represent the rental charges C.
b. How much will you pay if you return the DVD after 4 days? 7 days?

(1 point)
C = 4.70d; $18.80, $32.90
if d ≤ 5 then C = 4.70d, if d > 5 then C = 4.70d + 1; $17.80, $31.90
if d ≥ 5 then C = 4.70d, if d < 5 then C = 4.70d – 1; $17.80, $32.90
if d ≤ 5 then C = 4.70d, if d > 5 then C = 4.70d – 1; $18.80, $31.90
