Answer:
$375,000
Step-by-step explanation:
The computation of the amount included in the natural resource is shown below:
= Cost of land & natural resource rights + cost of extraction during year + equipment used for mining + exploration & drilling cost
= $200,000 + $35,000 + $100,000 + $40,000
= $375,000
Hence, all the cost is inlcuded for natural resource except asset retirement obligation for restoring the land as this is not relevant so we ignored it
