Answer:
Correct answer is C, $20,000,000
Step-by-step explanation:
Computation of depletion expense of natural resources has similar concept with depreciation of fixed asset. To calculate the depletion expense, we have to deduct first the salvage value (if there is) from the cost of an asset divided by the total estimated units available multiplied by the units extracted.
FORMULA:
(TOTAL COST - SAVAGE VALUE) / TOTAL ESTIMATED UNITS AVAILABLE x UNITS EXTRACTED
($100,000,000 - 0 ) / 2,500,000 x 500,000 = $20,000,000
