Answer
Debit Insurance Expense, $4,500 and credit Prepaid Insurance, $4,500.
Step-by-step explanation
Since, expenses are always debited and the unexpired amount of insurance will be remaining balance of $3,250 after the adjusting entry.
So, the amount that is being accounted for at the end of the period
= $7,750 - $3,250
= $4,500
Adjusting entry at December 31
debit credit
insurance expense $4,500
prepaid insurance $4,500
