A company that teaches self-improvement seminars is holding one of its seminars in Stafford.
The company pays a flat fee of $50 to rent a facility in which to hold each session.
Additionally, for every attendee who registers, the company must spend $18 to purchase
books and supplies. Each attendee will pay $23 for the seminar. Once a certain number of
attendee register, the company will be breaking even. What will be the company's total
expenses and revenues? How many attendees will that take?
