Answer: C.
Cost of Goods Sold
3,500
Merchandise Inventory
3,500
Step-by-step explanation:
A perpetual inventory system is a system thats uses records transactions that take place in real-time. Both the returns and the purchases are recorded immediately as they happen in the inventory account.
Under the perpetual inventory method, it should be noted that sales will be credited to the inventory while the purchases that are incurred will be debited to the inventory and it should be noted that the debit will be recorded in the account of the cost of goods sold.
Therefore based on the question, the journal entry to record the cost of goods sold would be:
Debit: Cost of goods sold $3500
Credit: Merchandise inventory $3500
Therefore, the correct option is C.
