Answer:
$10,000 increase in the net operating income
Explanation:
The computation of the overall impact is shown below:
= Change in contribution margin units - increase in the monthly advertising budget
= $17,100 - $7,100
= $10,000
The change in contribution margin units is computed below:
= New sales units × Contribution margin per unit
= 190 units × $90
= $17,100
And, the increase in the monthly advertising budget is a fixed expenses or fixed cost
Sales - variable cost = Contribution
Contribution margin - fixed expenses = Net operating income
