A tractor for over-the-road hauling is purchased for $95,000.00. It is expected to be of use to the company for 6 years, after which it will be salvaged for $4,000.00. Calculate the depreciation deduction and the unrecovered investment during each year of the tractors life.

Please show all calculations/equations

a) Use straight-line depreciation. Provide depreciation and book value for year 6.

depreciation for year 6 =

book value for year 6 =

b) Use declining-balance depreciation, with a rate that ensures the book value equals the salvage value. Provide depreciation and book value for year 6.

Depreciation for year 6 =

book value for year 6 =

c) Use double declining balance depreciation. Provide depreciation and book value for year 6

Depreciation for year 6 =

book value for year 6 =

d) Use double declining balance, switching to straight-line depreciation. Provide depreciation and book value for year 6.

Depreciation for year 6 =

book value for year 6 =
