    We can use an inequality.

    x = number of times one has to go.

    1.75x > 15.00

    1.75x / 1.75 > 15.00/1.75

    x = 15.00 / 1.75

    x > 8.57

    So when x > 9 time the membership is a better deal.

    On the 9th time it will be a better deal to have a membership. 9 times 1.75 is 15.75 which is more than 15
