Please help asap. Thank you so much, having trouble with question 2

Palm-West Products (A) 1. Background Valerie Preston formed Palm-West Products, Inc. in 2003 when she obtained an exclusive franchise to nationally distribute designer windows. Recent high sales growth of the base window (WIND-B), along with expected sales growth for a new enhanced window (WIND-E), requires adding management team members. Ms. Preston is keenly aware of other growth-oriented companies within the designer window sector that have run out of cash and gone into bankruptcy. Seeing potentially viable businesses fail particularly concerns Ms. Preston and, consequently, she wants to ensure that sufficient cash will be available to accommodate PWP's expected growth. She would like to present a financial plan to PWP's board of directors and needs a financial model that can be used to address questions from top management and members of the board of directors. She would also like to provide the board with a graphical cost-volume-profit analysis. 1.1 Company information From her prior education and work experience, Ms. Preston understands that the starting point for a financial plan is a reliable sales forecast. Thus, she conferred with Tom Sellers, the sales manager, along with an outside marketing consultant. Tom has studied industry sales and economic trends, along with other important market factors within the highly competitive designer window industry to establish a unit sales forecast. As shown in Exhibit 1, total monthly unit sales volume is expected to continue increasing over the third quarter, but with sales mix shifting toward the new enhanced window(WIND-E). Since Palm-West Products does not want to forfeit market share to competitors, it maintains a policy to never stock out of its windows. Prior to June, PWP sold only the basic window (WIND-B) at a price of $230 per unit. PWP purchases the WIND-B model from an overseas manufacturer for $155 per unit. In June, PWP began carrying a premium model WIND-P, priced at $380, which costs $225 from the manufacturer. The current sales mix is 80% WIND-B and 20% WIND-P. However, the company expects this mix to shift toward the premium model, along with ongoing competitive pricing pressure (see Exhibit 1). Palm-West Products (A) The company's monthly operating expenses (organized by cost behavior) are provided in Exhibit 2. For simplicity, the company assumes that all operating expenses are paid in cash during the month incurred, with the exception of depreciation and insurance expense. To simplify, assume no tax consequences.

Tom Sellers suggests that an advertising campaign at a cost of $50,000 per month, combined with increases in sales commissions from 5 percent to 8 percent will improve WIND-B and WIND-P sales and profitability. Calculate Net Income in July if the advertising campaign, and increase in sales commission increase sales in July of both products by 10 percent
