Answer:
Cost of goods sold = $836
Ending inventory = $315
Explanation:
a) Data and Calculations:
Date Description Units Unit Price Balance
Apr. 1 Inventory 12 $45 $540
Apr. 11 Purchase 13 $47 $1,151 ($540 + 13 * $47)
Apr. 14 Sale (18) $100 $315 ($7 * $45)
Sales revenue = $1,800 ($100 * 18)
Cost of goods sold = $836 ($47 * 13 + $45 * 5)
Ending inventory = $315 ($7 * $45)
b) Under the LIFO (Last in, First out) inventory valuation method, it is assumed that goods that were purchased closest to the selling date were the ones to be sold while those purchased earlier remain in inventory.
