Final answer:
The bad debt expense reported on the income statement is $980.
Step-by-step explanation:
The bad debt expense reported on the income statement can be calculated as the difference between the credit sales and the allowance for doubtful accounts. In this case, the credit sales were $1,000, and the allowance for doubtful accounts was $20. We can use the formula:
Bad Debt Expense = Credit Sales - Allowance for Doubtful Accounts
Bad Debt Expense = $1,000 - $20
Bad Debt Expense = $980
Therefore, the bad debt expense reported on the income statement is $980.
