Chapter 11, Problem 11.4E

To determine

Depreciation:

It refers to the reduction in the monetary value of fixed tangible assets over its useful life due to its wear and tear or, obsolescence. In other words, it is the method of distributing the cost of tangible fixed assets over its estimated useful life.

Straight-line method:

Under the straight-line method of depreciation, the same amount of depreciation is allocated every year over the estimated useful life of an asset. The formula to calculate the depreciation cost of the asset using the residual value is shown as below:

$\text{Depreciation = }\frac{\left(\text{Cost of the asset}-\text{Residual value}\right)}{\text{Estimated useful life of the asset}}$

To calculate: The amount of depreciation expenses on building and additional building.
