Answer:
depletion expense for 2018 6,019.18
Explanation:
$526,000 cost
1,031,000 tons
We have a cost(the mine) which is associate with an asset available, that will be depleted over time (iron ore)
So we have to distribute this cost at the rate this asset is being depleted:
cost/tonds of iron ore = depletion per ton
526,000/1,031,000 = 0.5101
Then we multiply this rate by the extracted amount of 2018
depletion expense for 2018
0.5101 x 11,800 = 6,019.18
