Siness Fitness Club uses straight-line depreciation for a machine costing $26,400, with an estimated four-year life and a $2,900 salvage value. At the beginning of the third year, Siness determines that the machine has three more years of remaining useful life, after which it will have an estimated $2,050 salvage value. Compute.
(1) The machine’s book value at the end of its second year.
(2) The amount of depreciation for each of the final three years given the revised estimates.
