Answer and Explanation:
The computation is shown below;
Cost of goods available for sale
Beg. inventory 50 units at $800 = $40,000
Add: Purchases 80 units at $820 = $65,600
Add: purchases 75 units at $840 = $63,000
Add: purchases 90 units at $850 = $76,500
Cost of goods available for sale $245,100
Now
Total number of bicycles is
= 50 + 80 + 75 + 90
= 295
And, Number of bikes sold is 235.
A. FIFO assumption
Cost of goods available for sale $245,100
less: Ending inventory 60 at $850 ($51,000)
Cost of goods sold $194,100
B.LIFO assumption
Cost of goods available for sale $245,100
Less Ending inventory
(50 units at $800 + 10units at $820) -$48,200
Cost of goods sold $196,900
C.Weighted average assumption
Cost of goods available for sale -$245,100
Less: ending inventory 60 units at $830.85 ($245,100 ÷ 295) $49,851
Cost of goods sold $195,249
D. Gross Margin under FIFO
Sales $352,500 (1,500 × 235)
Less: Cost of goods sold $194,100
Gros sMargin $158,400
E.Income tax expense under LIFO
Sales $352,500
Less: COGS $196,900
GM $155,600
Less: operating exp -$80,000
Income beforetax $75,600
Less: Tax expense (30% of $75,600) $22,680
Net Income $52,920
So, Income tax expense under the LIFO method is $ 22,680.
F. Tax saving using LIFO instead of FIFO
Gross margin under FIFO $158,400
Less: operating expense -$80,000
Gross margin under FIFO -$78,400
less: tax expense 30% of $78,400-$23,520
Net Income $54,880
Tax saving is ($23,520 - $22,680 ) = $840.00
