Answer:
$55,428.57
Explanation:
Depreciation is the systematic allocation of the cost of an asset to the income statement over the estimated useful life of that asset.
It is determined as the depreciable value of the asset over the estimated useful life of the asset where the depreciable value is the difference between the cost and salvage value of the asset
Mathematically,
Depreciation = (Cost - Salvage value)/Estimated useful life
Depreciation = (600,000 - 18,000) / 7
= $83,142.86
On January 1, 2020, after using the equipment for three years,
Asset Net book value
= $600,000 - 3($83,142.86)
= $350,571.43
the total estimated useful life has been revised to nine total years thus remaining 6 years and residual value is the same
Depreciation expense for 2020
= ($350,571.43 - $18,000) / 6
= $55,428.57
