Note: The full question has been attached as picture
 Cat Food Dog Food Fish Food 
Contribution margin per unit $4.50 $5.60 $2.70 
of product 
Contribution margin per unit $5.30 $3.57 $4.65 
of Direct materials 
The contribution margin per unit of direct materials is higher for Cat food than Dog and Fish food, hence the company should sell Cat food in order to maximize profit. 
 
Number of units of direct materials available = 3,200 units
Contribution margin per unit of direct materials of cat food = $5.30
Total profit = Number of units of direct materials available * Contribution margin per unit of direct materials of cat food 
Total profit = 3,200 unit * $5.30 
Total profit = $16,960
Thus, $16,960 is the maximum profit if the company can sell either of the three products.
