Please help, I will rate!! Thank you so much!

In evaluating the three potential suppliers (see Table below), weight schemes are provided as follows. Weight criteria for performance attributes: (Assigned) weight for price = 0.30, weight for quality = 0.40, and weight for delivery services = 0.30. Scoring scheme: Excellent (lowest price, lowest percentage of defects) = 5, good (second lowest price, second lowest percentage of defects, 95% on-time delivery) = 4, average (highest price, 90% on-time delivery) = 3, fair (80% on-time delivery) = 2, poor (defect rate 10% or higher) = 1. Hint: Do not forget to cross-multiply the performance ratings with their respective weights to calculate the total score. Performance Supplier A Supplier B Supplier C criteria Price $4 per unit $5 per unit $3 per unit 10% Quality 5% defects 1% defects defects Delivery services 95% on time 80% on time 90% on time Using the above information along with the given weighting and scoring schemes of the simple (alternative) weighted average method, which supplier should be the preferred source of supply? Supplier A Supplier B Supplier Both Supplier B and C
