Answer:
Dr Accounts payable $1000
Cr Cash $400
Cr Notes payable $600
Step-by-step explanation:
The $1000 owed was previously a credit in the accounts payable,since it has now been settled partly in cash and the remainder with notes payable,the accounts payable is debited with $1000.
Besides,the cash account should have witnessed an outflow of $400 and should be credited with $400.
Finally,$600 of the $1000 has been converted into notes payable instead of accounts payable and the notes payable should receive a credit of $600
