How do you calculate 20% off?

Multiply the original price by 0.20 to get the savings, then subtract from original price. Or multiply by 0.80 directly. Example: $60 × 0.80 = $48. You save $12.

How do you find the original price if you know the sale price and discount?

Original = sale price ÷ (1 - discount rate). If you paid $40 at 30% off: $40 ÷ 0.70 = $57.14 original price.
