Can you solve the question step by step and explain which formulas you use? The table given below lists the relevant cost items for a specific system purchase. Theoperating expenses for the new system are $10,000 per year, and the useful life of thesystem is expected to be five years. The salvage value for depreciation purposes is equalto 25% of the hardware cost.Cost ItemCostHardware$160,000Training$15,000Installation$15,000a) What is the Book Value (BV) of the device at the end of year three if the Straight Line(SL) depreciation method is used?b) Suppose that after depreciating the device for two years with the SL method, the firmdecides to switch to the double declining balance depreciation method for theremainder of the device's life (the remaining three years).
