On December 31, 2018, Allowance for Doubtful Accounts had a credit balance of $20,000. In 2019, ABC had net credit sales of $800,000. During 2019, $30,000 of uncollectible accounts receivable were written off. Past experience indicates that the allowance should be 5% of the balance in receivables (percentage of receivable basis). If the accounts receivable balance at December 31 was $300,000, what is the required adjusting journal entry at December 31, 2019? HTML Editore U Tx x? X WP [ 12pt Paragraph
