Answer:
The answer is A.
Dr Depreciation expense $100
Cr Accumulated depreciation $100
Step-by-step explanation:
The formula for depreciation using the straight-line method is:
(Cost of the asset - residual/salvage value) ÷ useful life of the asset.
Cost of the asset is $3,750
Salvage (residual) value is $150
Useful life is 3 years
So we have:
($3,750 - $150) ÷ 3years
=$3,600 ÷ 3
=$1,200
$1,200 is the depreciation expene for a year.
Therefore, monthly depreciation expense will be:
$1,200/100
=$100
According to the accounting rule, debit increases asset and expenses and vice-versa while credit decreases liability, equity, income and vice versa.
