Answer:
Depreciation Year 3 = $ 24000
Explanation:
Depreciation of year 1 using straight line method of depreciation
Dep Year 1 = Cost - Residual Value
Useful life
Dep Year 1 = 120,000-10,000
10years
Dep Year 1 = 11000
Dep Year 2 = 11000
In straight line method Depreciation amount remains constant in all years to follow
However in Year 3 residual amount and useful life were revised therefore depreciation amount also changed
Book Value at Year 3 = 120,000-22000
Book value Year 3 = 98000
Depreciation at Year 3 = book value- revised residua value
revised useful life
Dep Year 3 = 98000-2000
4 years
Depreciation Year 3 = $24000
