It's one time fee I believe, you don't pay Apple to submit an app. They also get a cut(30%) from your app every time it sells.

Seriously? So, along with the massive delay time, if you were selling a 1 dollar app you'd only gain .66 cents?
 
Don't waste your time. Study your books and do what you are supposed to do at 14. You have time to worry about money later.

But if you do want to get a head start on making money. Go outside and play with your friends. Learn to socialize. It will pay big time later! Consider it an investment.
