Your boss has told you to evaluate two ovens for Tink-the-Tinkers, a gourmet sandwich shop. After some questioning of vendors and receipt of specifications, you are assured that the ovens have the attributes and costs shown in the following table. The following two assumptions are appropriate: Three Small Ovens at $ 1 comma 200 Each Two Large Ovens at $ 2 comma 600 Each Original Cost $ 3 comma 600 $ 5 comma 200 Labor per year in excess of larger models $ 810 (total) $ 0 Cleaning/maintenance $ 780 ($ 260 each) $ 400 ($ 200 each) Salvage value $ 660 ($ 220 each) $ 1 comma 200 ($ 600 each) He is told to assume that a) the life of each oven is 5 years, and b) the company thinks it knows how to make 8% on investments no more risky than this one. a) Using the above, the NPV for Three Small Ovens = $ nothing (round your response to two decimal places and include a minus sign if the answer is negative).
