Marion Co. uses the percentage of receivables basis to record bad debt expense and concludes that 1% of accounts receivable will become uncollectible. Accounts receivables are $500,000 at the end of the year; and the allowance for doubtful accounts has a credit balance of $1,500. a. Prepare the adjusting journal entry to record the bad debt expense for the year. b. If the allowance for doubtful accounts had a debit balance of $800 instead of a credit balance of $1,500 prepare the adjusting journal entry for bad debt expense. The ledger of Seymour Company at the end of the current year shows Accounts Receivable $90,000; Credit Sales $780,000; and Sales returns of $40,000. If the Doubtful Accounts has a credit balance of $1,100 journalize the adjusting entry assuming bad debts are expected to be 10% of accounts receivable. If Allowance for Doubtful Accounts has a debit balance of $500 journalize the adjusting entry assuming bad debts are expected to the 8% of accounts receivable. Assume that 1% of Credit Sales are uncollectible and there is a credit balance of $1,100 in the Allowance Account
