Final answer:
To calculate the gross margin per unit for each product under the traditional costing system, subtract the cost of goods sold (COGS) from the selling price per unit for each product.
Step-by-step explanation:
The gross margin per unit can be calculated using the traditional costing system by subtracting the cost of goods sold (COGS) from the selling price per unit. The formula for gross margin per unit is:
Gross Margin per Unit = Selling Price per Unit - COGS per Unit
For each product, you need to know the selling price per unit and the COGS per unit. Plug in these values into the formula to calculate the gross margin per unit for each product.
