Answer:
$0.38
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 .
Depreciable value
= $42000 - $4000
= $38,000
Given that the plant asset will produce an estimated 100000 units over its useful life, the depreciation cost per unit
= $38,000 / 100000
= $0.38
