Answer:
The remaining useful life of the plant asset is 2 years.
Step-by-step explanation:
The depreciable cost of the asset is 44000 - 10000 = $34000
The straight line method charges a constant depreciation expense per year over the estimated useful life of the asset.
The depreciation expense per year is $3400.
The formula for straight line depreciation is,
Depreciation expense per year = (Cost - residual value) / estimated useful life
3400 = (44000 - 10000) / estimated useful life
3400 = 34000 / estimated useful life
Estimated useful life = 34000 / 3400 = 10 years
The accumulated depreciation has been charged for the amount of $27200. This represents a depreciation for 8 years.
27200 / 3400 = 8 years
Thus, the remaining useful life of the plant asset is 10 - 8 = 2 years
