Answer:
The residual value of the building is $19000
Step-by-step explanation:
depreciation expense=cost-residual value/useful life
cost is $67,000
useful life is 8 years
residual value is unknown
$6000=$67,000-x/8 years
$6000* 8 years=$67,000-x
$48,000=$67,000-x
x=$67,000-$48,000$
x=$19,0000
The residual value of the asset is $19,000
