Answer:
The correct answer is Decrease by $5,500.
Explanation:
According to the scenario, the computation of the given data are as follows:
First we calculate the previous operating income, by using following formula:
Previous operating income = ($8.5 - $5.25) × 10,000 units - $22,000
= $10,500
Now, we will calculate the current operating income by using following formula:
New operating income = ($7.5 - $5.25) 12,000 units - $22,000
= $5,000
So, the change in operating income can be calculated as
Change in operating income = New operating income - Previous operating income
= $5,000 - $10,500
= -$5,500 ( Negative shows Decrease)
= Decrease by $5,500.
