Nicholas is the facilities manager for Green Market Groceries. The store is remodeling and wants to determine which brand of freezer to use for its frozen goods section. The freezers vary by size, cabinet type, accessibility, refrigerant, and interliner. These variables affect both the purchase cost and the operating cost (e.g., energy consumption) of each freezer. Currently, the cost of energy per kilowatt hour (kwh) is $0.10. Green Market expenses capital purchases over a three-year period. Given the cost and capacity data below, calculate the "productivity" (i.e., the cubic feet of freezer space per dollar) for each freezer alternative. Which freezer brand would you recommend to Nicholas?
