Answer:
8,190
Explanation:
We need to calculate depreciation expenses each based on working-hour driver. Depreciation expense per working hour is calculated as below:
Depreciation per working hour = (Original cost - Salvage value)/Total expected life in working hour
= (90,000 - 8,100)/70,000 = 1.17
Total working hour per year =70,000/Expected life in year = 70,000/10 = 7,000
So, Depreciation expense for 2020 and 2023 each is 1.17 x 7,000 = 8,190
