    Video store movie rental plans. Plan A 25 membership fee plus 1.25 for movie. Plan B 40 for unlimited rentals. What number of movies rentals is plan B less than plan A?

    Let x equal the number of movies rented and C the cost for rentals
    Plan A: C = 1.25x + 25
    Plan B: C = 40

    Set up the inequality:
    1.25x + 25 > 40

    Subtract 25 from each side:
    1.25x > 15

    Divide each side of the inequality by 1.25
    x > 12
    So 13 rentals or more make Plan B less than Plan A.
