Answer:
$0.76 per ton or ore
Explanation:
to calculate the depletion expense per ton of re, we must first calculate the land's initial cost - salvage value = $1,890,400 - $264,000 = $1,626,400
now we divide by total expected ore reserves = 2,140,000 tons
depletion expense per ton of ore = $1,626,400 / 2,140,000 tons = $0.76 per ton
that means that the land will depreciate depending on the number of tons of ore extracted, not the time passed
