The discount formula

FAQ
How do I calculate a discount?
Multiply the original price by the discount percentage, then divide by 100 to get the savings. Subtract the savings from the original price to get the sale price. For example, 20% off $80 = $80 × 20 / 100 = $16 savings, so the sale price is $64.
What is the formula for sale price?
Sale Price = Original Price × (1 − Discount% / 100). For a 30% discount on $50: Sale Price = $50 × 0.70 = $35.
How do I find the original price from a sale price?
Divide the sale price by (1 − Discount% / 100). If something costs $70 after a 30% discount, the original price was $70 / 0.70 = $100.
