Worked examples

  1. $80 jacket at 25% off.

    1. 80 × (1 − 0.25) = 80 × 0.75

    Answer: $60 (you save $20)

  2. 20% off, then an extra 10% off at checkout.

    1. 0.80 × 0.90 = 0.72
    2. 1 − 0.72 = 0.28

    Answer: 28% total — not 30%

  3. You paid $51 after 15% off. What was the original price?
