Question #3: During the current year, Carpenter Company had net credit sales of 1,125,000. On January 1, Allowance for Doubtful Accounts had a credit balance of $27,000. During the year, $45,000 of uncollectible accounts receivable were written off. Past experience indicates that the allowance should be 10% of the balance in receivables (percentage of receivables basis). If the accounts receivable balance at December 31 was $300,000, what is the required adjustment to the Allowance for Doubtful Accounts at December 31?
