Final answer:
To calculate annual depreciation for Raine Industries machine using the straight-line method, subtract the residual value from the cost of the asset and divide it by the estimated useful life, resulting in a yearly expense of $3,800.
Step-by-step explanation:
The question from the student involves calculating the annual depreciation expense for a machine bought by Raine Industries. Firstly, we need to know the formula for depreciation using the straight-line method. The formula is (Cost of the asset - Residual value) / Estimated useful life. In this case, the cost of the asset is $21,000, the residual value is $2,000, and the estimated useful life is 5 years.
To calculate the annual depreciation expense:
- Subtract the residual value from the cost of the asset: $21,000 - $2,000 = $19,000.
- Divide that number by the estimated useful life of the asset: $19,000 / 5 years = $3,800.
The annual depreciation expense would be $3,800.
This calculation represents the amount of the asset's cost Raine Industries will allocate as an expense for each year of the machine's estimated useful life.
