Answer: Debit Account Payable $1600, Credit Cash $1600
Step-by-step explanation:
If the perpetual inventory system, and purchases are recorded through the use of a gross method, the correct journal entry to record the payment on July 28 will be to Debit Account Payable $1600, and then Credit Cash $1600.
In this case, we should note that we don't need any adjustment for discount. This is because the payment made was on the 28th of July.
