How am I going to get paid if I submit a paid app on the App Store?

I wanted to be an iOS Developer. And I want to know that if I had created a paid app and submit it on the app store, people will buy it. Let's say it's 0.99$. Then how much will i get and how I get paid from Apple. Ijust gave an example. I haven't create any thing YET. But I need to know, How I will get the money.
