Tarjee Florist is considering replacing an old refrigeration unit with a larger unit to store flowers. Because the new refrigeration unit has a larger capacity, Tarjee estimates that it can sell an additional $$9,000$ of flowers a year. $($The cost of the flowers is $$5,300).$ In addition, the new unit is energy efficient and should save $$2,332$ in electricity each year. It will cost an extra $$3,710$ per year for maintenance. The new refrigeration unit costs $$26,500$ and has an expected life of $10$ years. The old unit is fully depreciated and can be sold for an amount equal to disposal cost. At the end of $10$ years, the new unit has an expected residual value of $$5,194.$
