To raise funds for its community activities, a Lions Club chapter is negotiating with International Carnivals to bring its midway rides and

games to town for a three$-$day opening. The event will be held on part of the parking lot of a local shopping centre, which is to receive

$10\%$ of the gross revenue. The Lions Club members will sell the ride and game tickets at the site. International Carnivals requires either

$$15,000$ plus $30\%$ of revenue or $$10,000$ plus $50\%$ of revenue. The experience of other towns that have held the event is that

customers spend an average of $$10$ per person on rides and games.
