Final answer:
The book value of the equipment at December 31, 2016, is $28,160. The correct option is a.
Step-by-step explanation:
To calculate the book value of the equipment at December 31, 2016, we need to determine the accumulated depreciation for the equipment up to that date:
First, find the annual depreciation using the double-declining-balance method:
Depreciation expense = (2 / Useful life) x Book value at the beginning of the year
For 2015:
Depreciation expense = (2 / 10) x $44,000 = $8,800
For 2016:
Depreciation expense = (2 / 10) x ($44,000 - $8,800) = $7,040
The accumulated depreciation at the end of 2016 is the sum of the depreciation expenses for 2015 and 2016:
Accumulated depreciation = $8,800 + $7,040 = $15,840
To find the book value at December 31, 2016, subtract the accumulated depreciation from the cost:
Book value at December 31, 2016 = Cost - Accumulated depreciation = $44,000 - $15,840 = $28,160
Therefore, the answer is $28,160 (option a).
