Frequently asked questions
How do you calculate a discount?
Multiply the price by the discount percent and divide by 100 to get the saving, then subtract it from the price. 20% off 80 saves 16, so the price is 64.
What happens when two discounts stack?
They apply one after the other, not added together. 20% then 10% off is a 28% total discount, not 30%.
How do I find the original price from the sale price?
Divide the sale price by (1 − discount ÷ 100). If 64 is after 20% off, the original is 64 ÷ 0.8 = 80.
