When using perpetual inventory system the jounal entry to record the cost of merchandise sold is?

In a perpetual inventory system, the journal entry to record the cost of merchandise sold involves debiting the Cost of Goods Sold (COGS) account and crediting the Inventory account. For example, if the cost of merchandise sold is $1,000, the entry would be:

<code>Debit: Cost of Goods Sold $1,000
Credit: Inventory $1,000
</code>

This entry reflects the reduction in inventory and recognizes the expense associated with the goods that have been sold.
