## How to Calculate a Weighted Average

### Formula

**Weighted Average = Sum of (Score x Weight) / Sum of Weights**

Weights should add up to 100%. Higher-weighted categories have more impact on your final grade.

Exemplo Resolvido

Homework (90%, 20%), Midterms (85%, 30%), Final (78%, 30%), Participation (95%, 20%).

  1. Homework: 90 x 0.20 = 18.0
  2. Midterms: 85 x 0.30 = 25.5
  3. Final: 78 x 0.30 = 23.4
  4. Participation: 95 x 0.20 = 19.0
  5. Total: 85.9 / 1.00 = 85.9%
