Final answer:
The depreciation expense for 2022 would be $70,000. Therefore, the correct option is B.
Step-by-step explanation:
To determine the depreciation expense for 2022, we first need to calculate the remaining book value of the equipment at the beginning of 2022. Using the sum-of-the-years'-digits method, we calculate the accumulated depreciation after three years:
- Year 1: 8/36 * $840,000 = $186,667
- Year 2: 7/36 * $840,000 = $163,333
- Year 3: 6/36 * $840,000 = $140,000
The accumulated depreciation after three years is $490,000. So, the remaining book value at the beginning of 2022 is $840,000 - $490,000 = $350,000.
Since the equipment now has a remaining life of 5 years (8 - 3), we can divide the remaining book value by the remaining life to calculate the straight-line depreciation expense for 2022: $350,000 / 5 = $70,000.
