Final answer:
To calculate depreciation using the straight-line method for 2022 and 2023, divide the cost of the machine minus the salvage value by the useful life. For the declining-balance method, multiply the book value by double the straight-line rate. For units-of-activity, divide the cost of the machine minus the salvage value by the total units of activity and multiply by the machine usage.
Step-by-step explanation:
To calculate the depreciation using the straight-line method, we use the formula:
Depreciation Expense = (Cost - Salvage Value) / Useful Life
For 2022 and 2023:
Depreciation Expense = ($104,000 - $8,000) / 8 = $12,000 per year
To calculate the depreciation using the declining-balance method, we use the formula:
Depreciation Expense = Book Value x Double the Straight-line Rate
For 2022 and 2023, the straight-line rate is 1 / 8 = 0.125
Depreciation Expense = Book Value x 0.125 = ($104,000 - Accumulated Depreciation) x 0.125
For units-of-activity, the formula is:
Depreciation Expense per Unit = (Cost - Salvage Value) / Total Units of Activity
Depreciation Expense = Depreciation Expense per Unit x Machine Usage
Depreciation Expense per Unit = ($104,000 - $8,000) / 80,000 = $0.45 per hour
Depreciation Expense = $0.45 x 2,900 = $1,305 for 2022.
