(a) Determine the amount of the annual depreciation.
(b) Determine the book value at the end of the tenth year of use.
(c) Assuming that at the start of the eleventh year the remaining life is estimated to be eight years and the residual value is estimated to be $6,000, determine the depreciation expense for each of the remaining eight years.
