Answer:
$1.40
Explanation:
The total contribution margin is determined by deducting variable costs from sales during the period:
[tex]CM = \$27,000 -\$11,880\\CM = \$15,120[/tex]
Assuming a production of 10,800 units, the contribution margin per unit is:
[tex]CM_u = \frac{\$15,120}{10,800}\\CM_u =\$1.40[/tex]
The contribution margin per unit in July is $1.40.
