Answer:
$8,718.75
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
Annual depreciation
= (540,000 - 75,000)/40
= $11,625
Depreciation between 1 January and 1 September 2018 (9 months)
= 9/12 * $11,625
= $8718.75
