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:

Sales	$ 1,571,000
Variable expenses	657,300
Contribution margin	913,700
Fixed expenses	1,005,000
Net operating income (loss)	$ (91,300)

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:

	Division
East	Central	West
Sales	$ 431,000	$ 640,000	$ 500,000
Variable expenses as a percentage of sales	50%	37%	41%
Traceable fixed expenses	$ 267,000	$ 330,000	$ 207,000

Required:

1. Prepare a contribution format income statement segmented by divisions.

2-a. The Marketing Department has proposed increasing the West Division's monthly advertising by $20,000 based on the belief that it would increase that division's sales by 14%. Assuming these estimates are accurate, how much would the company's net operating income increase (decrease) if the proposal is implemented?

2-b. Would you recommend the increased advertising?
