The formula and answer for this problem is below, can someone show me how each of the calculations were identified? I'm having problems getting to the correct answer. Infinity Designs, an interior design company, has experienced a drop in business due to an increase in interest rates and a corresponding slowdown in remodeling projects. To stimulate business, the company is considering exhibiting at the Home and Garden Expo. The exhibit will cost the company $12,000 for space. At the show, Infinity Designs will present a slide show on a PC, pass out brochures that are printed previously, (the company printed more than needed), and show its portfolio of previous
jobs.
The company estimates that revenue will increase by $36,000 over the next year as a result of the exhibit. For the previous year, profit was as follows:

		Revenue		$201,000
		Less:
		Design supplies (variable cost)	$15,500
		Salary of Samantha Spade (owner)	80,000
		Salary of Kim Bridesdale (full time employee)	55,000
		Rent	18,000
		Utilities	6,000
		Depreciation of office equipment	3,600
		Printing of advertising materials	700
		Advertising in Middleton Journal	2,500
		Travel expenses other than depreciation of autos (variable cost)	$3,000
		Depreciation of company cars	9,000
Required:
Calculate the impact of the exhibit on company profit.

Correct Answer: (20,686.57)

Supplies as a percentage of Revenue = Supplies/Total Revenue Travel as a percentage of Revenue = Travel/Total Revenue Now: Increase in Revenue MINUS Cost of Exhibit Space Increase in Supplies (Increase * Supply Percentage) Increase in Travel (increase * Travel Percentage) = Increase in Profit
