#3 for perpetual, the inventory would be $98 as well. Remember that you can never have an entry that doesn't balance.

Otherwise, it's all correct. Good job! Difficult to learn both methods at the same time.

The purchases were recorded at full price, hence the credit is correctly recorded for the full price of $100. The difference of $2 represents purchase discounts. The entry is:

Debit Cash 98
Debit Purchase discounts 2
Credit Merchandise Inventory 100

The inventory was already paid for and the discount already removed from inventory, meaning the net cost of the inventory is now in inventory at 98.

Sorry, did not notice the entry of November 5. I stand corrected

Well, if you'd sit at the computer instead of standing... :-)
