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.
You estimate that 30 people will attend the class, but you want to change this input.
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.
