Part 1 b
Gross Profit = Sales - Cost of Sales
Sales = ( 80 x $8.00 + 120 x $8.75 + 100 x $9.00) = $2,590
Cost of Sales = (100 x $5 + 150 x $6 + 160 x $7) = $2,520
Therefore,
Gross Profit = $2,590 - $2,520
= $70

Debit : Cost of Sales (50 x $6.00 + 50 x $7) $650
Credit : Revenue (100 x $9.00) $900
Credit : Inventory (50 x $6.00 + 50 x $7) $650
Part 2 b
Gross Profit = Sales - Cost of Sales
Sales = ( 80 x $8.00 + 120 x $8.75 + 100 x $9.00) = $2,590
Cost of Sales = ($400 + $700 + $650) = $1,750
Therefore,
Gross Profit = $2,590 - $1,750
= $840
Step-by-step explanation:
Hie, see the attached the full question as images below
Part 1
Note that the question in this part requires us to use the Periodic Inventory System. In Periodic Inventory system, Inventory Valuation and calculation of Cost of Goods Sold is done at the end of the Period, in this case at the end of the month of January.
Part 2
Again it is important to note that the question in this part requires us to use the Perpetual Inventory System. In Perpetual Inventory system, Inventory Valuation and calculation of Cost of Goods Sold is done at the after each and every transaction made.
Overall Comment
The Company use of FIFO should be considered in both the Periodic Inventory System in Part 1 and Perpetual Inventory System in Part 2. FIFO method assumes that the first goods received by the business will be the first ones to be delivered to the final customer.
That said, Cost of Sales for Part 1 are determined and recognized at the end of the period and Cost of Sales for Part 2 are determined and recognized after every sale transaction made
