Answer:
bad debt expense 97,866 debit
 Allowance for Doubtful Accounts 97,866 credit
Explanation:
We are given the table for the aging method from which we extract the
Total for Allowance for Doubtful Accounts 106,106
Now, as currently the allwoance for doubtful accounts has a balance of 8,240 we need to adjust to make up the difference
106,106 adjusted balance - 8,240 current balance = 97,866 adjustment
we will credit the allowance and recognzie this amount of bad debt expense
This way we are matching our net account receivables with our estimation of what we expect to collect
