How to work out 10% off $30
- Turn the discount into a decimal: 10 ÷ 100 = 0.1.
- Multiply by the price: 0.1 × $30 = $3 — that is the amount you save.
- Subtract the saving from the price: $30 − $3 = $27.
Mental-math shortcut: Drop the last digit (move the decimal one place left) to get the discount. (1% of $30 is $0.30, so 10% is $0.30 × 10 = $3.)

Method & sources
Saving = price × discount ÷ 100, and sale price = price − saving. Amounts are rounded to the cent only for display. Stacked discounts multiply rather than add — 20% off and then another 20% off is 36% off in total, not 40% — and sales tax, where it applies, is charged on the discounted price.
