During May, the company had credit sales of $40,400 and collected $34,300 from customers. It also wrote off a certain amount of uncollectible receivables during the month and recorded a certain amount of bad debts expense at the end of the month. No accounts that were written off during the month were subsequently recovered. At the end of May, after all journal entries had been recorded and posted, the balance in Accounts Receivable was $33,400 while Allowance for Doubtful Accounts had a balance of $4,800.
