Frequently Asked Questions
How do I calculate 20% off?
Multiply the price by 0.20 to get the discount amount, then subtract from the original price. Example: $50 × 0.20 = $10 off → $40 final price.
How do I find the original price from a sale price?
Divide the sale price by (1 − discount/100). Example: $40 at 20% off → $40 ÷ 0.80 = $50 original.
Can I stack multiple discounts?
Apply discounts sequentially. 20% then 10% off $100: $100 × 0.80 = $80, then $80 × 0.90 = $72. This is NOT the same as 30% off.
