    357.83/.72=x

    496.986=x

    Answer:without the discount, it would have cost her $497

    Step-by-step explanation:

    Let x represent the amount that the gravel would have cost her without the discount.

    Her brother works for the gravel company and got her a 28% discount. The value of the discount would be

    28/100 * x = 0.28 * x = 0.28x

    It mans that the amount that she paid for the gravel is

    x - 0.28x = 0.72x

    If Jamie paid $357.83 for the gravel (without tax), it means that

    0.72x = 357.83

    x = 357.83/0.72

    x = 496.99

    Approximately $497
