Clean Duds Laundromat has an industrial water softener that enhances the water quality used in its washing machines. The water softener is approaching the end of its useful life and must be either overhauled or replaced. Details of the two alternatives are shown below. If the company overhauls its current water softener, then it will be usable for eight more years. If. instead, a new water softener is purchased, it will be used for eight years, after which it will be replaced. The new water softener will be considerably more energy efficient. resulting in a substantial reduction in annual operating costs. as shown below: 03:22" Softener Water SOItBnB-I' Purchase cost: new 17,000 S 23,500 $ Remaining book value $ 13,500 - Overhaul needed now 5 8,500 Annual cash operating costs $ 10,500 3 7,200 Salvage value now $ 3,800 Salvage value eight years from now $ 1.900 5 4.800 Clean Duds computes depreciation on a straight-line basis.
