Explanation:
a) Data and Calculations:
Accounts receivable $250,000
Less: Allowance for doubtful accounts 15,000
b) The allowance for Doubtful Accounts will increase by $7,000 to $22,000.  As a result, the Uncollectible Expense will be debited with $7,000 while the Allowance for doubtful accounts will be credited with $7,000.  This brings the total of Allowance for Doubtful Accounts to $22,000 in accordance with the new estimate based on the aging of accounts receivable.
