Blue Corporation acquires a coal mine at a cost of $512,400. Intangible development costs total $122,000. After extraction has occurred, Blue must restore the property (estimated fair value of the obligation is $97,600), after which it can be sold for $195,200. Blue estimates that 4,880 tons of coal can be extracted. If 854 tons are extracted the first year, prepare the journal entry to record depletion.
