Answer:
the numbers are missing, so I looked for a similar question:
Purchases Sales Units Unit Cost Units Selling Price/Unit
3/1 Beginning inventory 100 $40
3/3 Purchase 60 $50
3/4 Sales 60 $80
3/10 Purchase 200 $55
3/16 Sales 70 $90
3/19 Sales 90 $90
3/25 Sales 60 $90
3/30 Purchase 40 $60
the requirements are:
calculate COGS and ending inventory under FIFO, LIFO and weighted average.
since this company uses the periodic inventory level we must first determine the total cost of goods available for sale:
3/1 Beginning inventory 100 $40
3/3 Purchase 60 $50
3/10 Purchase 200 $55
3/30 Purchase 40 $60
total goods available for sale = 400 units, at a total cost of $20,400
total units sold = 60 + 70 + 90 + 60 = 280 units
ending inventory = 120 units
under FIFO:
ending inventory = (40 x $60) + (80 x $55) = $6,800
COGS = $20,400 - $6,800 = $13,600
under LIFO:
ending inventory = (100 x $40) + (20 x $50) = $5,000
COGS = $20,400 - $5,000 = $15,400
under weighted average:
ending inventory = ($20,400 / 400) x 120 = $6,120
COGS = $20,400 - $6,120 = $14,280
