Part 1: Breakeven Analysis for a Conference. The Greenville Center for Business Analytics is an outreach center that collaborates with industry partners on applied research and continuing education in business analytics. One of the programs offered by the center is a quarterly Business Intelligence Conference. Each conference features three speakers on the real-world use of analytics. Each corporate member of the center (there are currently 12) receives five free seats to each conference. Nonmembers wishing to attend must pay $80 per person. Each attendee receives breakfast, lunch, and free parking. The following are the costs incurred for putting on this event: Rental cost for the auditorium $150 Registration processing $7.50 per person Speaker costs 3@$1,200 = $3,600 Continental breakfast $3.50 per person Lunch $8.00 per person Parking $10.00 per person a) 10 points. Use MS Excel drawing tools to build an influence diagram that models the factors that influence total profit for the conference. b) 10 points. Build a spreadsheet model that calculates a profit or loss based on the number of nonmember registrants. c) 10 points. Use Goal Seek to find the number of nonmember registrants that will make the event break even. d) 10 points. The parameters in the current model represent the costs that management believes are most likely for the current year. Consider the following three possible scenarios

	Worst Case	Mixed Case	BestCase
Registration Processing cost Per person	12.00	7.00	7.00
Continental Breakfast per person	$5.50	$5.50	$3.00
Cost per Speaker	$1,600	$1,200	$1,000

Assume the Conference will have 150 nonmember attendees and that all other inputs are the same as above. Use Scenario Manager to generate a summary report that gives the profit for each of these three scenarios. Will the conference be profitable in all cases?
