Answer:
$49,000
Explanation:
The computation of the book value at December 31, 2019 is shown below:-
Depreciation expenses = (Cost of equipment - Residual value) ÷ Service life
= ($60,000 - $5,000) ÷ 5
= $55,000 ÷ 5
= $11,000
So,
Book value at December 31, 2019 = Cost of the equipment - Depreciation expenses
= $60,000 - $11,000
= $49,000
Therefore for computing the book value of December 31, 2019 we simply applied the above formula.
