Apex Fitness Club uses straight line depreciation for a machine costing $ 23,860, with an estimated four year life and a $ 2,400 salvage value. At the beginning of the third year, Apex determines that the machine has three more years of remaining useful life, after which it will have an estimated $ 2,000 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.
