Final answer:
Using the straight-line method, the annual depreciation for the stamping machine is calculated to be $270,000 by subtracting its residual value from the cost and then dividing by the useful life.
Step-by-step explanation:
To calculate the annual depreciation using the straight-line method, subtract the machine's residual value from its cost and then divide by the useful life of the asset.
The cost of the stamping machine is $1,425,000 and the residual value is $75,000. The estimated useful life is 5 years. Therefore, the annual depreciation is calculated as follows:
Annual Depreciation = (Cost - Residual Value) / Useful Life
Annual Depreciation = ($1,425,000 - $75,000) / 5 years
Annual Depreciation = $1,350,000 / 5 years
Annual Depreciation = $270,000
The correct answer is a) $270,000.
