Answer:
$3.28 per ton
Step-by-step explanation:
Total value = Land + Estimated restoration costs
= $7,440,000 + 1,440,000
= $8,880,000
Value for depletion = Total value - Salvage value
= $8,880,000 - $940,000
= $7,940,000
Per ton Depletion:
= Value for depletion ÷ Recoverable reserves
= $7,940,000 ÷ 2,420,000 tons
= $3.28 per ton
