Answer:
The total liabilities at end of September is $5,000
Step-by-step explanation:
The $21,000 received from business owner is capital which would have been credited to capital and debited to cash.
The purchase of office equipment meant that cash decreased by $4000,a credit of $4,000 and a credit of $5,000 to notes payable while the $9000 is debited to equipment account.
The insurance expense,utility bill,rent as well as the purchase of office furniture were all cash settled and had no liability impact,hence the only liability outstanding at month end is the notes payable on office equipment of $5,000
