If a company reports $100,000 in gross sales and has $20,000 in returns and allowances, and $5,000 in discounts, the net sales would be calculated as $100,000 - $20,000 - $5,000 = $75,000.
The quarterly financial report shows that the net sales have increased by 15% from the previous quarter, indicating a positive trend in revenue after accounting for returns and discounts.
