Answer:
The quantity demanded will decrease by 2%.
Explanation:
This can be determined using the elasticity formula as follows:
e = Percentage change in quantity demanded change / Percentage change in price ........ (1)
Where;
e = elasticity of demand for college textbooks = -0.1
Percentage change in quantity demanded change = ?
Percentage change in price = 20%
Substituting the values into equation (1) and solve for Percentage change in quantity demanded change
-0.1 = Percentage change in quantity demanded change / 20%
Percentage change in quantity demanded change = -0.1 * 20% = -0.02, or -2%
Since the Percentage change in quantity demanded change is negative 2%, it implies that the quantity demanded will decrease by 2%.
Answer:
$10,000 increase in the net operating income

The computation of the overall impact is shown below:
= Change in contribution margin units - increase in the monthly advertising budget
= $17,100 - $7,100

= 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
