EXERCISE $6-11$ Segmented Income Statement $$ LO$6-40$ Wingate Company, a wholesale distributor of electronic equipment, has been experiencing losses for some time, as shown by its most recent monthly contribution format income statement: In an effort to resolve the problem, the company would like to prepare an income statement segmented by division. Accordingly, the Accounting Department has developed the following information: Required: Prepare a contribution format income statement segmented by divisions. The Marketing Department has proposed increasing the West Division's monthly advertising by $$15,000$ based on the belief that it would increase that division's sales by $20\%.$ Assuming these estimates are accurate, how much would the company's net operating income increase $($decrease$)$ if the proposal is implemented?

Thank You!
