Answer:
$72,600
Step-by-step explanation:
Ending balance of the account receivable can be calculated by adding credit sales in beginning balance and deducting any account receivable written-off.
As we have the ending balance of account receivable, we need to calculate credit sales by following formula:
Account receivable Ending Balance = Account receivable Beginning Balance + Credit Sales - Bad Debt - Ending Balance
$320,000 = $260,000 + Credit Sales - $12,600
$320,000 = $247,400 + Credit Sales
Credit Sales = $320,000 - $247,400 = $72,600
