Answer:
84
Supplier X
Step-by-step explanation:
The computation of supplier Y score is shown below:
Supplier Y Score is
= Supplies Y rating × weight
= 80 × 0.5 + 90 × 0.1 + 85 × 0.3 + 95 × 0.1
= 40 + 9 + 25.5 + 9.5
= 84
As we can see that the supplier score of X is 85 which is greater than the supplier score of Y
Hence, the supplier X should be selected by the RBS company
