Answer:
Option (d) is correct.
Step-by-step explanation:
Contribution margin per unit for Product A:
= Selling price - variable cost
= $87 - $46
= $41
Contribution margin per unit for Product Z:
= Selling price - variable cost
= $108 - $53
= $55
contribution margin per composite unit:
= (Contribution margin per unit for Product A × 5) + (Contribution margin per unit for Product Z × 2)
= ($41 × 5) + ($55 × 2)
= $205 + $110
= $315
