Final answer:
The weighted total score for the supplier is calculated using the provided factor weights and supplier ratings, resulting in a score of 7.05.
Step-by-step explanation:
To calculate the weighted total score for a supplier with ratings in three categories, we can use the given factor weights and ratings to perform the following calculation:
- Freshness rating: 6.5 with a weight of 0.5
- Lot size rating: 7 with a weight of 0.2
- Cost rating: 8 with a weight of 0.3
The weighted total score can be calculated as:
(Freshness score × Freshness weight) + (Lot size score × Lot size weight) + (Cost score × Cost weight)
(6.5 × 0.5) + (7 × 0.2) + (8 × 0.3) = 3.25 + 1.4 + 2.4 = 7.05
Hence, the weighted total score for the supplier is 7.05, which corresponds to option A when rounded to two decimal places.
