I'm confused about specific identification. Can you please show your work or where the answers come from? I'd like to fully grasp the concept. Thanks! Please note-- some of the answers in the table are probably incorrect. Dr. Doolittle starts a merchandising business on December 1 and enters the following three inventory purchases. Dr. Doolitle uses a perpetual inventory system. On December 15, Dr. Doolittle sells 15 units at $20 each. Of the units sold, eight are from the December 7 purchase and seven are from the December 14 purchase. Determine the costs assigned to ending inventory when costs are assigned based on specific identification.
