Answer and Explanation:
The computation of the contribution margin per pound for each of the three products is shown below:
As we know that
Selling price per pound - Variable cost per pound = Contribution margin
For Product K1
= $155.8 - $91
= $64.8
For Product S5
= $108.92 - $90
= $18.92
For Product G9
=$205.55 - $136
= $69.55
Now the contribution margin per pound is
For Product K1 = Contribution margin ÷ Pound
= 64.8 ÷ 4.2
= 15.43 per pound
For Product S5 = Contribution margin ÷ Pound
= 18.92 ÷ 4.1
= 4.61 per pound
For Product G9 = Contribution margin ÷ Pound
= 69.55 ÷ 5.3
= 13.22 per pound
