Assume the following information for Jones Company:

Deluxe Chair:

Contribution margin per chair $90

Machine hours to produce 1 chair 3 hours

Executive Chair:

Contribution margin per chair $100

Machine hours to produce 1 chair 5 hours

Machine hours is the constraint resource.

The contribution margin per machine hour is:

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
