How it's calculated
- Find the discount: 30% of $100 = $100 × 0.3 = $30.00
- Subtract it from the price: $100 − $30.00 = $70.00
Shortcut: with 30% off you pay 70% of the price, so multiply $100 × 0.7 = $70.00 in one step.
Sales tax, if any, is usually added after the discount and isn't included here.
