Additionally, for every attendee who registers, the company must spend $3 to purchase books and supplies. Each attendee will pay $15 for the seminar. Once a certain number of attendees register, the company will be breaking even. How many attendees will that take? What will be the company's total expenses and revenues?

The latex got the Q a bit messed up....I assume the company pays flat fee 120 for rental and $3 for supplies for each antendee

the atendees pay $ 15 ea

 

120 + 3x = 15 x    solve for x

120 = 12x

x = 10   

 

At 15 atenddees expenses will equal revenues    120 + 3(10) = 150
