Answer:
depletion expense recognize over the first year: 400,000 dollars
Step-by-step explanation:
it cost 2,500,000 the right to extract 10,000 tons
To obtain therate we divide the cost over the expected tons of materials
rate per ton: 2,500,000 / 10,000 = 250 dollars
Now we calculate the depletion based on the amount extracted on the first year:
first year extractions: 1,600 tons
depletion expense: 1,600 tons x 250 dollars = 400,000
