Higher Level: Compound Percentages
Multiple percentage changes:
- NOT additive: 10% increase then 10% decrease ≠ 0% change
- Multiply multipliers: +10% then -10% = 1.1 × 0.9 = 0.99 = -1%
- Order doesn't matter: +20% then +30% = ×1.2 ×1.3 = ×1.56 = +56%
Example: Price increases 20%, then decreases 15%
Overall multiplier = 1.2 × 0.85 = 1.02 = +2% overall
