Hello your question is incomplete below is the complete question

answer :

2a) Increases by $25,176

Explanation:

1) Attached below is the contribution format income statement

2a) Determine by how much the net operating income will change

monthly advertising increment = $25,000

Assumed increase in division's sales = 16%

first step : determine increment in contribution margin of west division

change in net operating income = 50176 - monthly advert increment

                                                     = 50176 - 25,000 = $25,176 ( increases )
