Answer:
Depreciation charge is $6,000
Step-by-step explanation:
The depreciation charge using straight line method of depreciation can be computed using the below formula:
depreciation charge=cost -salvage value/useful life
cost is $50,000
salvage value is the same as residual value which is worth of the asset after useful life is $2,000
useful life is the number of years the asset is expected to e put into use which is 4 years
depreciation charge=($50,000-$2,000)/4=$12,000 per year
The depreciation for the year ended 31 st December 2017 is a six month depreciation amount,hence the depreciation amount is $6,000($12,000*6/12)
