Explanation:
The adjusting entry is as follows
Insurance expense A/c Dr $4,800
To Prepaid insurance A/c $4,800
(Being the insurance expense is recorded)
The computation is shown below:
= Beginning balance + debited amount - unexpired insurance amount
= $6,600 + $2,300 - $4,100
= $4,800
So while preparing the adjusting entry, we debited the insurance expense account and credited the prepaid insurance account
