Weighted average multiplies each performance rating by its assigned weight (converted to a decimal) and then sums those products.

1. Relevant knowledge points and concepts
- Weighted average (weighted mean): overall score = sum(rating_i × weight_i).
- Percent weights must be converted to decimals (e.g., 30% = 0.30).
- Valid weighting requires the weights to sum to 100% (they do here).

2. Complete reasoning process step by step
Convert each weight to a decimal and multiply by its rating, then add results.

3. Calculations with intermediate steps
- On-Time Delivery: 80 × 30% = 80 × 0.30 = 24.00
- Quality: 95 × 25% = 95 × 0.25 = 23.75
- Order Accuracy: 90 × 20% = 90 × 0.20 = 18.00
- Price: 100 × 15% = 100 × 0.15 = 15.00
- Cost Reduction: 75 × 5% = 75 × 0.05 = 3.75
- Innovation: 80 × 5% = 80 × 0.05 = 4.00

Sum the weighted contributions:
24.00 + 23.75 + 18.00 + 15.00 + 3.75 + 4.00 = 88.50

4. Why the correct answer is correct
Each criterion contributes proportionally to its importance; multiplying each rating by the corresponding weight yields the criterion’s contribution to the overall performance. Summing these contributions gives the supplier’s composite score of 88.5, reflecting both performance levels and their relative importance.

5. Why other approaches would be incorrect
- Using an unweighted (simple) average would ignore the specified importance of criteria and produce a different score. 
- Mis-converting percentages (e.g., using 30 instead of 0.30) would give incorrect, inflated results.
- There are no alternative answer choices provided; the weighted calculation above is the appropriate method.

6. Conclusion
The calculated overall performance score is 88.5, which matches the provided answer (88.5).
