Part $3$

Beyond$$ costs, however, Wanda has three other criteria considered important in the selection of a supplier. The following table shows all the$$ criteria, their$$ weights, and the scores for all of them except total$$ costs, where a score of $1\mathrm{.}0$ indicates$$ "poor" and $10$ indicates$$ "superior." Because all three suppliers have done business with Wanda Lux$$ before, management will assign a score of$"10"$ to the supplier with the lowest total annual$$ cost$,$ a score of$"8\mathrm{.}5"$ for the next lowest$$ cost$,$ and a score of$"7\mathrm{.}0"$ for the worst cost of the three.
