Answer:
7
Step-by-step explanation:
Depreciation expense using the straight line depreciation method = (Cost of asset - Salvage value) / useful life
Useful life isn't given
Cost of asset = $80,0000
Salvage value = $20,000
Depreciation expense = $5,000
$5,000 = ($80,000 - $20,000) / x
$5,000 = $60,000 / x
X = 12
The useful life is 12 years
If accumulated depreciation is $25,000, the number of years so far would be $25,000 / $5,000 = 5 years
Remaining year = 12 - 5 = 7 years
