Final answer:
The gross margin can be calculated by subtracting the Cost of Goods Sold and Sales Returns and Allowances from the Sales Revenues. In this case, the gross margin is $55,000.
Step-by-step explanation:
The gross margin can be calculated by subtracting the Cost of Goods Sold (COGS) and Sales Returns and Allowances from the Sales Revenues. Gross Margin = Sales Revenues - (COGS + Sales Returns and Allowances)
In this case, the COGS is $90,000 and the Sales Returns and Allowances is $5,000. The Sales Revenues can be determined by subtracting the Sales Discounts ($3,000) from the given Sales Revenues ($150,000).
Gross Margin = $150,000 - ($90,000 + $5,000) = $55,000
