To calculate the contribution margin for 5,700 units, let's follow these steps:

Step 1: Calculate Contribution Margin per Unit

Given:

• Total Contribution Margin = $123,200 (for 5,600 units)

$\text{Contribution Margin per Unit} = \frac{123,200}{5,600} = 22 \, \text{per unit}$

Step 2: Calculate Contribution Margin for 5,700 Units

Now that we know the contribution margin per unit is $22, we can find the total contribution margin for 5,700 units:

$\text{Total Contribution Margin for 5,700 units} = 5,700 \times 22 = 125,400$

Final Answer:

The total contribution margin for 5,700 units is:
