Answer:
Net operating income is $300
Explanation:
We know that,
The net operating income = Sales - variable cost - fixed expenses
And, the contribution margin = Sales - variable cost
So, contribution margin - fixed expenses = Net operating income
Since we have to compute the net operating income for 3,500 units So, first we have to compute the contribution margin per unit which is shown below:
= Contribution margin ÷ number of units
= $48,000 ÷ 4,000 units
= $12
Now for 3,500 units, the contribution margin would be
= 3,500 units × $12
= $42,000
So, the net operating income would be
= $42,000 - $41,700
= $300
The fixed expenses would not be changes. It remains constant
