Brenda opened a pool and spa store $in$ a lively shopping mall and finds business $tobe$ booming but she often stocks out $of$ key items customers want. The $28-$ounce bottle $of$ Super Algaecide $(SA)is$ a high margin SKU, but $it$ stocks out frequently. Ten $SA$ botles come $in$ each box, and Brenda orders boxes from a vendor $160$ miles away. Brenda $is$ busy running the store and seldom has time $to$ review store inventory status and order the right quantity $at$ the right time. She collected the following data:
