The proper adjusting entry on December 31 is, D. Debit Insurance Expense, $4,700; credit Prepaid Insurance, $4,700.

Explanation:

The entry of prepaid insurance made earlier was $8,150 and on December 31, it was calculated that the unexpired amount of insurance was $3,450. So first we will calculate the amount of prepaid insurance which has been expired,

$8,150 -  $3,450 = $4,700

To record the expired prepaid insurance, we will first debit prepaid insurance expense with $4,700 and then credit prepaid insurance with $4,700.

Prepaid Insurance is an asset and it will decrease by a credit of $4,700, so that the remaining balance in prepaid insurance account is $3,450 which is the remaining unexpired prepaid insurance.

u = 30

continuing your method

= +

subtract from both sides

= - thus

= -

= ⇒ u = 30
