Swifty Corporation acquires a coal mine at a cost of $424,000. Intangible development costs total $106,000. After extraction has occurred, Swifty must restore the property (estimated fair value of the obligation is $84,800), after which it can be sold for $169,600. Swifty estimates that 4,240 tons of coal can be extracted. If 742 tons are extracted the first year, prepare the journal entry to record depletion.
