How do I calculate 20% off a price?

Multiply the original price by 0.20 to find the discount amount, then subtract from the original. Or simply multiply by 0.80 for the final price.

What is the original price if I know the sale price and discount?

Divide the sale price by (1 – discount%). For example, a $80 item at 20% off had an original price of $80 ÷ 0.80 = $100.

How do I calculate successive discounts?

Apply discounts one at a time. A 20% then 10% discount is not 30% off — it's 28% off (you pay 80% then 90% of that).
