After four years, a machine had an accumulated depreciation of $38,000. The machine originally had an anticipated life of eight years and a salvage value of $5,000. If the current book value after four years is $43,000 and the machine has only two years of usable life left, how much will be depreciated in year five and in year six using the straight-line method of depreciation, and assuming the salvage value is still $5,000? Please show equations, thanks.
