I want to start by saying The Outsiders is a superb book.
Okay so, Sodapop struggles with both internal and external conflicts, being the middle child and all. The main internal conflict he deals with is how to deal with his brothers constant bickering. He always has to be the middle man during there fights.
It's 6 and 25.
25*6= 150
25+6= 31
I think that number 3 is the answer you're looking for.
