Answer:
C. $231,000
Step-by-step explanation:
Straight line depreciation is calculated as Cost less salvage value divided by useful life of the asset which is $1,120,000-$70000=$1,050,000
Then divide it by the useful life which is 5 years.:
$1,050,000/5=$210,000
The asset has been fully depreciated at year 5 which is 2018, therefore, add the gain made on sales to the accumulated depreciation:
$210,000+$21,000=$231000
