Answer:
Ending inventory = $2,185.47
Cost of goods sold = $36,424.53
Explanation:
500 units sold at $120
Date Transaction Units Unit Cost Total Cost
Jan. 1 Beg. inventory 40 $68 $2,720
May. 5 Purchase 270 $71 $19,170
Nov. 3 Purchase 220 $76 $16,720
Total 530 $72.849 $38,610
Ending inventory = (530 - 500) x $72.849 = $2,185.47
Cost of goods sold = 500 x $72.849 = $36,424.53
When you use the weighted average method, you add the total amount of purchases + beg. inventory, and then divide by the total amount of units.
