What is 15% off $40?

How it's calculated

1. Find the discount: 15% of $40 = $40 × 0.15 = $6.00
2. Subtract it from the price: $40 − $6.00 = $34.00

Shortcut: with 15% off you pay 85% of the price, so multiply $40 × 0.85 = $34.00 in one step.

Sales tax, if any, is usually added after the discount and isn't included here.
