Answer:
$54,000
Step-by-step explanation:
For computation of Depreciation Expense for the year ending 31 Dec first we need to compute the depreciation under straight line method for the year which is shown below:-
Depreciation under straight line method for the year = (Cost - Residual value) ÷ Estimated useful life
= ($600,000 - $60,000) ÷ 10
= $540,000 ÷ 10
= $54,000
Depreciation expenses = (Depreciation under straight line method for the year ÷ 12) × From Jan 1 to Dec 31
= ($54,000 ÷ 12) × 12
= $4,500 × 12
= $54,000
