Answer:
a.A credit to Accumulated Depreciation of $45,000
Step-by-step 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
The entries for recording depreciation are
Debit Depreciation expense
Credit Accumulated depreciation
Depreciation on equipment
= $450,000/10
= $45,000
