During its first year of operations, Drone Zone Corporation (DZC) bought goods from a manufacturer on account at a cost of $63,000. DZC returned $9,300 of this merchandise to the manufacturer for credit on its account. DZC then sold $51,000 of the remaining goods at a selling price of $77,600. DZC records sales returns as they occur and then records estimated additional returns at year-end. During the year, customers returned goods that had been sold at a price of $8,100. These goods were in perfect condition, so they were put back into DZCs inventory at their cost of $5,300. At year-end, DZC estimated $10,310 of current year merchandise sales would be returned to DZC in the following year; DZC estimates $6,600 as its cost of this merchandise.
