Answer:
$7,312.50
Explanation:
The computation of the depreciation expense for 2017 is shown below:
Book Value is
= Cost - Accumulated Depreciation
= $150,000 - {[($150,000 - $24,000) Ă· 12 ] Ă— 7y}
= $150,000 - [($126,000 Ă· 12 ) Ă— 7]
= $150,000 - ($10,500 Ă— 7)
= $150,000 - $73,500
= $76,500
Now the depreciation expense for 2017 :
= ($76,500 - $18,000) Ă· (15 - 7) years
= $58,500 Ă· 8 years
= $7,312.50
