Could someone please help. I cannot figure out exactly how to journalize these transactions.

Completed a large delivery job, billed the customer $2000, and received a promise to collect the $2000 in one week,

Collected $500 in advance for delivery service to be performed later.

Paid office rent, $500. THis rent is not paid in advance.

Prepaid insurance, $600

Paid $100 on account.

Paid cash dividends of $1900

Any help would be greatly appreciated

2) Debit Cash for the amount
Credit Unearned Service revenue for the amount

3) Debit Rent Expense for the amount

5) Debit Accounts Payable for the amount
