How to work it out
- Work out the discount: 15% of 80 = 0.15 × 80 = 12
- Take it off the price: 80 − 12 = 68
- Check: Add the saving back: 68 + 12 = 80.
Another method. In one step: you pay 85% of the price, so 0.85 × 80 = 68. Both methods always give the same answer.
In a spreadsheet: =80*(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.
