Answer:
(a) FIFO (b) LIFO (c) weighted
average cost:
Cost of goods available for sale $2,600 $2,600 $2,600
Ending inventory 1,540 1,500 1,516
Sales $1,400 $1,400 1,400
Cost of goods sold 1,060 1,100 1,083
Gross profit $340 $300 $317
Explanation:
a) Data and Calculations:
Units Unit Cost Unit Selling Price
July 1 Beginning Inventory 40 $ 10 $400
July 13 Purchase 200 11 2,200
July 25 Sold ( 100 ) $ 14 (1,400)
July 31 Ending Inventory 140
July 31 Goods available 240
Average unit cost = $10.83 ($2,600/240)
FIFO:
Cost of goods available for sale $2,600 ($400 + $2,200)
Ending inventory 1,540 (140 * $11)
Sales $1,400 ($14 * 100)
Cost of goods sold 1,060 (40 * $10 + 60 * $11)
Gross profit $340
LIFO:
Cost of goods available for sale $2,600 ($400 + $2,200)
Ending inventory 1,500 (40 * $10 + 100 * $11)
Sales $1,400 ($14 * 100)
Cost of goods sold 1,100 (100 * $11)
Gross profit $300
Weighted Average:
Cost of goods available for sale $2,600 ($400 + $2,200)
Ending inventory 1,516 (140 * $10.83)
Sales $1,400 ($14 * 100)
Cost of goods sold 1,083 (100 * $10.83)
Gross profit $317
