Expert Solution

(a)

To determine

Straight-line Depreciation: 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 salvage value is shown as below:

Depreciation cost = (Original cost of the asset-residual value)Estimated useful life of the asset

To determine: the amount of annual depreciation.

### Explanation of Solution

Determine the amount of annual depreciation.

Cost of the equipment =$1,200,000 Estimated residual Value =$250,000

Estimated useful life =40 years

AnnualDepreciation = (Original cost of the asset-residual value)Estimated useful life of the asset
