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 $ $1,597,000$

Variable expenses $533,420$

Contribution margin $1,063,580$

Fixed expenses $1,170,000$

Net operating income $($loss$)$ $ $(106,420)$

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 $ $357,000$ $ $680,000$ $ $560,000$

Variable expenses as a percentage of sales $46\%23\%38\%$

Traceable fixed expenses $ $285,000$ $ $320,000$ $ $204,000$

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 $$29,000$ 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?
