Answer:
$54,400
Step-by-step explanation:
The balance in the refund liability account would be calculated as;
Ending balance of sales return allowance = Opening balance of allowance + Expected sales return - Actual sales return
Given that;
Opening balance = $33,400
Expected return = $740,000 × 7% = $51,800
Actual return = $30,800
Therefore,
Ending balance of sales returns = $33,400 +$51,800 - $30,800 = $54,400
The balance in the refund liability account at the end of 2021 is $54,400
