Answer: $474,000
Step-by-step explanation:
Net revenue = Sales revenue - Sales discounts - Sales returns - Sales allowance
= 540,000 - 13,000 - 33,000 - 20,000
= $474,000
Sales returns reduces the sales figure because the goods were returned and therefore not paid for.
Sales discounts are a reduction as well because they reduce the amount paid by buyers.
Sales allowances also reduce the value of sales.
