Can you please show me how to do this problem so that I can figure it out on my own if I get another one. And my professor gave me the second picture, but I'm not sure how it goes with this question.

1.12. 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? \\begin{tabular}{l|c} & Alaskan Seal \\\\ \\hline Purchase cost & \\( \\$ 3,270 \\) \\\\ \\hline Daily energy consumption (kwh) & 3.61 \\\\ Cost per kwh & \\( \\$ 0.10 \\) \\\\ Daily energy cost & \\( \\$ 0.36 \\) \\\\ Daily purchase cost & \\( \\$ 2.99 \\) \\\\ Total cost & \\( \\$ 3.35 \\) \\\\ Volume (cu \\( \\mathrm{ft}) \\) & 25 \\\\ Productivity \\( (\\mathrm{cu} \\mathrm{ft} / \\$ \\) ) & \\( \\$ 7.47 \\) \\\\ Cost/cu \\( \\mathrm{ft} \\) & \\( \\$ 0.13 \\) \\end{tabular}
