2. (20 points) Create a spreadsheet to calculate your projected total costs, total revenues, and total profits for giving a seminar on cost estimating. Make the following assumptions: You will charge $600 per person for a two-day class (i.e., the class fee). Your fixed costs include $500 total to rent a room for both days, setup fees of $400 for registration, and $300 for designing a postcard for advertising. You will not include your labor costs for this estimate, but you estimate that you will spend at least 150 hours developing materials, managing the project, and giving the actual class. You would like to know what your time is worth given different scenarios. You will order 5,000 postcards, mail 4,000, and distribute the rest to friends and colleagues. Your variable costs include the following: a. $5 per person for registration plus 4 percent of the class fee per person to handle credit card processing, assume that everyone pays by credit card b. $.40 per postcard for printing if you order 5,000 or more c. $.25 per postcard for mailing and postage d. $25 per person for beverages and lunch e. $30 per person for class handouts Calculate your profits based on each of the following numbers of students who might attend: 10, 20, 30, 40, 50, and 60. In addition, calculate what your time would be worth per hour based on the number of students. (Please for this question, you need only to submit your Excel file)
