Answer: $5,700
Explanation:
First find the depreciation for the first 4 years.
= (26,100 - 3,300) / 8
= $2,850
Accumulated depreciation in year 4= 2,850 * 4 = $11,400
Net book value in year 4 = 26,100 - 11,400 = $14,700
Revised useful life means only 2 years are left.
New depreciation = (14,700 - 3,300) / 2 = $5,700
