I need help preparing adjusting entry for this problem please

Based on your inquiries, you note that $67,000 of accounts receivable had been written off during the year. The clerk had debited bad debt expense for $67,000 and credited Accounts Receivable for $67,000. When $15,000 of accounts previously written off had been collected, the accountant debited cash and credited sales. The company uses the allowance method based on the aging of accounts receivable. Based on this method DeeDee determines that uncollectible accounts are $86,000 at the end of 2017
