Answer:$19500
Explanation:
The provision for doubtful debts accounts is an account that shows the amount of estimated debts that are expected to go bad at the end of the year. The estimated amount at the end of a year is debited to income account, credited to debtors account and left as a credit balance on the provision for doubtful debts accounts.
If at the end of a new year a new estimate is made which differs from the current estimated figure, then the account is adjusted to show the entire new estimate and that is why the answer to the question is 3% of $650,000 = $19,500.
