Answer :
Answer:
The company's net operating income would increase by 2.1875%.
Explanation:
Let the selling price for each unit be $y
Initial quantity sold per month before increase in the advertising budget = 6400 units
Initial income = $6400y
New monthly sales after increase in advertising budget = 6400 + 1400 = 6540 units
New income = $6540y
Increase in income = $6540y - $6400y = $140y
Percentage increase in income = (increase in income ÷ initial income) × 100 = ($140y ÷ $6400) × 100 = 0.021875 × 100 = 2.1875%
