    (old – new) / old

    Percent Discount = (Original Price – Sale Price) / Original Price x 100%
    ($113.49 – $99.00)/$113.49 x 100% = 12.77% discount
    A percent discount is really just the amount of money you save divided by the old price. Very simple!

    %/100 = is/of
    x/100 – 14.49/113.49 ($113.49 original price – $99 sale price = apprix $14.49)
    cross multiply
    113.49x = 1449
    x = 1449/113.49
    x = 12.8% discount
    proof: .128 x 113.49 =approx $14.53
    another way to solve
    x/100 = 99/113.49
    113.49x = 9900
    x = 9900/113.49
    x = 87.23% = % paid
    100% – 87.23% = approx. 12.8% discount
