i just need help on question 3 with the total budgeted cost in RED BOX

You have been recruited by a former classmate, Susanna Wu, to join the finance team of a company that she founded recently. The company produces a unique product line of hypoallergenic cosmetics and relies for its success on an aggressive marketing program. The company is in a start-up phase and therefore has no significant history of expenses and revenues upon which to rely for budgeting and planning purposes. Given the restriction on available funds (most of the available capital has been used for new product development and to recruit a management team), the control of costs, including marketing costs, is thought by the management team to be essential for the short-term viability of the company. You have held a number of intensive discussions with Susanna and John Thompson, director of marketing for the firm. They have asked you to prepare an estimated budget for marketing expenses for a month of operations. You are provided with the following data, which represent average actual monthly costs over the past three months Cos Amount Sales commissions $126,000 Sales staff salaries 43,000 Telephone and mailing 41,000 Rental-office building 22,000 Gas (utilities) 12,600 Delivery charges 71,800 Depreciation office furniture 9,800 Marketing consultants 25,600 Your discussions with John and Susanna indicate the following assumptions and anticipated changes regarding monthly marketing expenses for the coming year Sales volume, because of aggressive marketing, should increase by 16 To meet competitive pressures, sales prices are expected to decrease by 8 Sales commissions are based on a percentage of sales revenue Sales staff salaries, because of a new hire, will increase by 16%, regardless of sales volume Because of recent industrywide factors, rates for telephone and mailing costs, as well as delivery charges, are expected to increase by 8%. However, both of these categories of costs are variable with Sales Volume Rent on the office building is based on a two-year lease, with 19 months remaining on the original lease Gas utility costs are largely independent of changes in sales volume. However, because of industrywide disruptions in supply, these costs are expected to increase by 17%, regardless of changes in sales Volume Depreciation on the office furniture used by members of the sales staff should increase because of new equipment that will be acquired. The planned cost for this equipment is $14,400, which will be depreciated using the straight-line (SL) method, with no salvage value, over a three-year useful life Because of competitive pressure, the company plans to increase the cost of marketing consultants by $4,500 per month
