Answer:
the information regarding the sales was missing, so I looked for similar questions:
The March 5 sale consists of bikes from beginning inventory, the March 17 sale consists of bikes from the March 9 purchase, and the March 27 sale consists of four bikes from beginning inventory and eight bikes from the March 22 purchase.
Date Transactions Units Unit Cost Total Cost
March 1 Beginning inventory 20 $ 250 $ 5,000
March 5 Sale ($400 each) 15
March 9 Purchase 10 270 2,700
March 17 Sale ($450 each) 8
March 22 Purchase 10 280 2,800
March 27 Sale ($475 each) 12
March 30 Purchase 9 300 2,700 $ 13,200
Cost of good sold under specific identification:
March 5 sale = $250 x 15 = $3,750
March 17 sale = 8 x $270 = $2,160
March 27 sale = 12 x $280 = $3,360
total COGS = $9,270
Ending inventory = $13,200 - $9,270 = $3,930
