Data and Calculations:
Date Description Units Unit Cost Total Cost
Jan. 1 Inventory 50 $100 $5,000
Mar. 10 Purchase 70 $110 7,700
Aug. 30 Purchase 30 $118 3,540
Dec. 12 Purchase 50 $120 6,000
Total 200 $22,240
Dec. 31 Ending inventory 80
Number of units sold 120 (200 - 80)
Average cost per unit = $111.20 ($22,240/200) under the periodic system
FIFO:
Ending inventory = $9,540 (30 x $118 + 50 x $120)
Cost of goods sold = $12,700 ($22,240 - $9,540)
LIFO:
Ending inventory = $8,300 (50 x $100 + 30 x $110)
Cost of goods sold = $13,940 ($22,240 - $8,300)
Weighted-Average Cost:
Ending inventory = $8,896 (80 x $111.20)
Cost of goods sold = $13,344 (120 x $111.20)
