Answer:
$72,290
Explanation:
Straight-line depreciation is when the same amount is depreciated every year over the life of the asset. It is calculated as:
(Cost of asset - salvage value) / number of useful years
In the initial depreciation method, depreciation for 2019 =
($800,000 - $29000) / 20 = $38550
The depreciation expense for 2020 is also $38550.
In January 2021, the depreciation changed. In order to account for this, the following formula is used:
(Cost - Revised Residual Value - Accumulated Depreciation) / Revised Remaining Useful Life
For this year, it would be :
($800,000 - 0 - $77100*) / 10 = $72,290
(*This includes the addition of the depreciation of the asset in the previous years. i.e. $38550 x 2)
Thus, depreciation expense for the year ending 31, December 2021 is $72,290
