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) 130 days old, $11,700; (2) 3190 days old, $4,700; and (3) more than 90 days old, $2,700. 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) 20 percent, respectively. At December 31 (end of the current year), the Allowance for Doubtful Accounts balance was $770 (credit) before the end-of-period adjusting entry is made.

Required:

1. Prepare a schedule to estimate an appropriate year-end balance for the Allowance for Doubtful Accounts.

2. What amount of Bad Debt Expense should be recorded on December 31?

3. If the unadjusted balance in the Allowance for Doubtful Accounts was a $570 debit balance, what amount of Bad Debt Expense should be recorded on December 31?
