How to work it out

  1. Work out the discount: 15% of 15 = 0.15 × 15 = 2.25
  2. Take it off the price: 15 − 2.25 = 12.75
  3. Check: Add the saving back: 12.75 + 2.25 = 15.

Another method. In one step: you pay 85% of the price, so 0.85 × 15 = 12.75. Both methods always give the same answer.

In a spreadsheet: =15*(1-15%). Taking the percentage of the price gives the saving, not the price you pay. Subtract it, or multiply by the share that is left.

What the result means

After 15% off, you pay 85% of the price: 12.75 instead of 15, a saving of 2.25.
