Answer:
For deluxe chair contribution margin per machine hour is $ 30
For Executive Chair contribution margin per machine hour is $ 20
Explanation:
Given:
For the Deluxe Chair,
The contribution margin per chair = $ 90
Machine hours required to produce 1 chair = 3 hours
Therefore,
the contribution margin per machine hour
= ( contribution margin per chair / Machine hours required per char )
or
= $ 90 / 3 = $ 30
Now, for the Executive Chair,
Contribution margin per chair = $ 100
Machine hours to produce 1 chair = 5 hours
Therefore,
the contribution margin per machine hour
= ( contribution margin per chair / Machine hours required per char )
or
= $ 100 / 5 = $ 20
