Final answer:
The bad debt expense for the period is calculated by adding the existing debit balance in the allowance for doubtful accounts and the estimated uncollectible accounts for the year, which results in $49,000. The correct answer is d. $49,000.
Step-by-step explanation:
The question pertains to accounting for uncollectible accounts under the allowance method. When the allowance for doubtful accounts has a debit balance of $9,000 before adjustment, and the estimated uncollectible accounts for the year is $40,000, the bad debt expense for the period must bring the allowance account to the correct new balance. Therefore, the bad debt expense will be the sum of the existing debit balance and the new estimate. This means:
Bad debt expense = Existing debit balance + New estimate
Bad Debt Expense = $9,000 + $40,000
Bad Debt Expense = $49,000
The correct answer is d. $49,000.
