Answer:
$808
Step-by-step explanation:
FIFO method assumes that the units to arrive first, will be sold first. This means that the Cost of Goods sold will be based on earlier (old) prices.
Also, the periodic inventory system ensures that the cost of sales and the ending inventory are determined at the end of the period. For this question, the end of period is monthly.
Step 1 : Determine Number of Units Sold
Units Sold = Units available for sale - Inventory Units
= (200 + 120 + 120) - 160
= 440 - 160
= 280 units
Step 2 : Determine Cost of Sales
Cost of Sales = 200 units x $5 + 80 units x $5.40
= $1,432
Step 3 : Determine Gross Profit
Gross Profit = Sales - Cost of Goods Sold
= ($8 x 280 units) - $1,432
= $2,240 - $1,432
= $808
Conclusion
The gross profit for the month is $808
