Wanda Lux must select a supplier for a plastic bottle and proprietary dispenser for its new hair shampoo. Three suppliers have placed bids; at Wanda's request, all bids are for a shipping quantity $(Q)$ of

$20,000$ bottles with annual requirements $($D$)$ of $40,000$ units. Wanda's factory operates $250$ days a year. The following table shows each supplier's price, estimated annual freight costs, and current

lead times; management has added estimates for holding costs and administrative oversight costs for each supplier.

a$.$ Which of the three suppliers will provide the lowest annual cost to Wanda Lux?

Using is the lowest cost alternative, with annual total costs to Wanda Lux of $$.($Enter your response rounded to the nearest whole number.$)$

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.
