Final answer:
The annual depreciation expense for the machine purchased by Lavaux Inc. using the straight-line method is $2,750, calculated by subtracting the salvage value from the cost of the machine and dividing by the machine's useful life.
Step-by-step explanation:
To calculate the depreciation expense for the machine purchased by Lavaux Inc. using the straight-line depreciation method, we would use the following formula:
Depreciation Expense = (Cost of the asset - Salvage value) / Useful life of the asset
In this scenario, the cost of the asset is $25,000, the salvage value is $3,000, and the useful life is 8 years.
Depreciation Expense = ($25,000 - $3,000) / 8
Depreciation Expense = $22,000 / 8
Depreciation Expense = $2,750 per year
This is the annual expense Lavaux Inc. would report for the use of the machine.
