    The sale price was 30% off the original price, which means it was on sale for 70% of the original cost (100% - 30% = 70%)

    To find the original cost, divide the sale price by the percent of the original cost:

    21 / 0.70 = 30

    The original price was $30

    check:

    30 x 0.3 = 9 (amount of discount)

    30 - 9 = 21 (sale price)
