Answer:
Depreciation expense for 2021 will be $14700
Explanation:
The straight line method charges a constant depreciation expense each period throughout the useful life of the asset. The depreciation expense per period under the straight line method is calculated as follows,
Depreciation expense = (Cost - Residual value) / Useful life of the asset
Depreciation expense = (81000 - 7500) / 5
Depreciation expense = $14700
