Apex Fitness Club uses straight-line depreciation for a machine costing $21,700, with an estimated four-year life and a $3,000 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 $2,550 salvage value.

Compute (1) the machines book value at the end of its second year and (2) the amount of depreciation for each of the final three years given the revised estimates. (Do not round your intermediate calculations. Negative amount should be indicated by a minus sign.)

Book value at the end of year 2:
Cost
Accumulated depreciation 2 years
Book value at point of revision

Revised depreciation (Years 3-5)
Book value at point of revision
Less revised salvage value
Remaining depreciable cost
Years of life remaining
