Answer:
$2,580
Explanation:
Depreciation = (Cost - Residual Value)/ Useful life
Yearly depreciation = ($43-800 - $3000)/8 = $5100
At the end of Year 5, total depreciation would be = $5100 X 5 = $25,500
Net book value at the end of year 5 = $43,800 - $25,500 = $18,300
Year 6, the extra ordinary repair that extended the useful life would be capitalized. Book value = $18,300 + $7,500 = $25,800
As 5 years have been expended, the remaining useful life would be 15-5 = 10 years
Depreciation expense year 6 = $25,800/10 = $2,580
