Explanation:

Depreciation is the systematic allocation of the cost of an asset to the income statement over the estimated useful life of that asset.

It is determined as the depreciable value of the asset over the estimated useful life of the asset where the depreciable value is the difference between the cost and salvage value of the asset

Mathematically,  

Depreciation = (Cost - Salvage value)/Estimated useful life

To record depreciation expense,

Debit Depreciation expense account (p/l)

Cr Accumulated depreciation

From the given information,

Monthly depreciation = $4,320/12

= $360
