Final answer:
The depreciation for 2020 using the double-declining balance method is $6,400.
Step-by-step explanation:
To calculate the depreciation for 2020 using the double-declining balance method, you will first need to determine the asset's useful life. In this case, the useful life is 8 years. The double-declining balance method involves dividing the straight-line rate by 2 and then multiplying it by the asset's beginning book value. The straight-line rate is calculated by dividing 100% by the useful life in years.
Step 1: Calculate the straight-line rate: 100% / 8 = 12.5%.
Step 2: Calculate the depreciation amount for 2020: $65,600 x 12.5% = $8,200.
However, the double-declining balance method only depreciates an asset until its book value reaches the salvage value, so we need to check if the depreciation amount exceeds the remaining book value (($65,600 - $8,200) - $5,200). If it does, we need to adjust the depreciation amount to ensure it does not depreciate more than the remaining book value. In this case, the depreciation for 2020 would be adjusted to $6,400.
