FAQ
- How do I calculate a discount?
- Multiply the original price by the discount percentage, then subtract. For 20% off $100: $100 x 0.20 = $20 savings, sale price is $80.
- How do I find the original price from a sale price?
- Divide the sale price by (1 - discount%). For an $80 item at 20% off: $80 / 0.80 = $100 original price.
- What is the difference between "X% off" and "pay X% of the price"?
- "30% off" means you pay 70%. "Pay 30%" means 70% off. These are a common source of confusion in advertising.
