How it works
The amount saved is the original price times the percent off, divided by 100. The sale price is the original price minus the amount saved.
To work backward, divide the sale price by one minus the percent off, written as a fraction of 1, to get the original price.
Worked example
Something priced at $80.00 with 25% percent off sells for $60.00, which saves $20.00.
Questions
Are stacked discounts added together?
No. A second discount is taken off the price after the first one, so the total is smaller than adding the two percentages.
Does this include sales tax?
No. Tax is added separately, after the sale price, so add it on top where it applies.
Can I use it to check a receipt?
Yes. Enter the price on the tag and the percent shown, and compare the sale price with the receipt.
