Answer:
Therefore, the change in total contribution margin is equal to change in net operating income, so there is no change in fixed expenses and will not be affected.
Explanation:
The computation as per given question is given below:-
Variable cost per unit
= $48 + $65
= $113
Contribution margin per unit
= $240 - $113
= $127
Unit Monthly sales
= 1,500 + 240
= 1,740
Total contribution margin
= 1,740 × $127
= $220,980
Total contribution margin
= 1,500 × $192
= $288,000
So, change in total contribution margin and net operating income
= $288,000 - $220,980
= $67,020
Therefore, the change in total contribution margin is equal to change in net operating income, so there is no change in fixed expenses and will not be affected.
