Answer:
The depreciation expense for the first two years is $72,000.
Step-by-step explanation:
Under straight-line method, depreciation expense is (Cost - Residual value) / No of years = ($400,000 - $40,000) / 10 years = $36,000 yearly depreciation expense.
Using this method, the depreciation expense for the first two years is $36,000 x 2 years = $72,000. This amount is regarded as the accumulated depreciation at the end of Year 2 while the net book value would be $400,000 - $72,000 = $328,000.
