Brown Cow Dairy uses the aging approach to estimate Bad Debt Expense. The balance of each account receivable is aged on the basis of three time periods as follows: (1) 1 to 30 days old, $11,100; (2) 31 to 90 days old, $4,100; and (3) more than 90 days old, $2,100. For each age group, the average loss rate on the amount of the receivable due to uncollectibility is estimated to be (1) 6 percent, (2) 11 percent, and (3) 25 percent, respectively. At December 31 (end of the current year), the Allowance for Doubtful Accounts balance was $710 (credit) before the end-of-period adjusting entry is made. Required: 1.
