Dana Hall wants to make sure that all options are being considered. In addition to the option of purchasing the Coldline brand refrigerators $($$$10,000$ cost per unit, $$100,000$ installation costs, $$200,000$ annual savings for five years$),$ the $99$s are also considering some less$-$expensive models. Westlake brand refrigerators will cost only $$6,000$ each, and have the same total installation will cost $($$$100,000)$ to install all $60$ new units. These refrigerators will have a useful life of only four years and will produce net cost savings of only $$100,000$ per year because they are not as energy$-$ efficient. A friend who also works in the restaurant industry has told Dana that the Arctic Air units are terrific. Dana$$s research shows that a comparable Arctic Air unit will cost $$11,500$ per unit, with total installation costs of $$120,000,$ and these refrigerators will last for $7$ years; annual cost savings are estimated to be $$175,000.$ Based on an analysis of his company$$s financial position and goals, Dana has set the discount rate at $8\mathrm{.}0\%$ percent. Some of the stakeholders for the refrigeration project are not very good at understanding the time value of money, so calculate a basic Benefit$-$Cost Ratio for each of the projects outlined in the preceding question.
