Answer:
b. $240,000
Step-by-step explanation:
The computation of the total contribution margin is shown below:
Contribution margin per machine hour for Product X is
= $50 ÷ 5 hours
= $10/hour
And,
Contribution margin per machine hour for Product Y is
= $64 ÷ 8 hours
= $8/hour
Now
= 80% × 25,000 hours
= 20,000 hours used for Product X
Now
= 20,000 hours ÷ 5 hours per unit
= 4,000 units
And,
= 4,000 units × $50
= $200,000
And,
= 5,000 hours ÷8 hours per unit
= 625 units × $64
= $40,000
so, Total CM is
= $200,000 + $40,000
= $240,000
