You get to the entrance of the tent to find a guard in the way.

"Sorry girls, the tent is full." You look in behind the guard to see that she is right. There must be fifteen-thousand people in there. Every seat is stuffed (there are ten thousand) and there are about five thousand people sitting on a hill behind the tent. You know that, if the woman let you in, you'd be able to find room to sit on the hill. You don't feel like going on any more rides, if you can't get in, you might as well phone your dad, and have him pick you up.

Do you want to try to convince the guard to let you in, or do you want to give up, and phone your dad?
