Using EXCEL The University of Cincinnati 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 Symposium. Each symposium features three speakers on the real-world use of analytics. Attendees must pay $75 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 cost  • Speaker costs    • Continental breakfast cost  • Lunch cost    • Parking cost    $ 8.50 per person 3 * $ 800 = $ 2,400 $ 4.00 per person $ 7.00 per person $ 5.00 per person a) Build a spreadsheet model that calculates a profit or loss if 150 people registered for the event.  b) Use Goal Seek to find the number of registrants that will make the event breakeven. c) The center for Business Analytics is considering a refund policy for no-shows and people who registered but not attended to the event will be refunded 50% of the price. Historically 15% of the registrants do not attend to the meeting. Based on this, modify your spreadsheet model you developed in Part A. The center pays the caterer for breakfast and lunch based on the number of registrants (not the number of attendees). However, the center pays for parking only for those who attend. What is the profit (or loss) if 135 people registered for the event? d) Use a two-way data table to show how profit changes as a function of number of registrations and the no-show percentage of registrants. Vary the number of registrations from 90 to 170 in increments of 10 and the percentage of no-shows from 10% to 30% in increments of 5%. e) Consider three scenarios: Base Case % of registrants who do not show Worst Case 20% Best Case Number of registrations 30% 10% 140 100 180 All other inputs are the same as in part a. Use Scenario Manager to generate a summary report that gives the profit for each of these three scenarios. What is the highest profit? What is the lowest profit?
