How do you start a bussiness for teen

You cant start off thinking about the money, The first six months or fewer you won't be getting much. Do something you truly love and want to do. If I were you I'd start off working at places like a dairy queen or pizza hut something like that you are most likely to make money like that. but if you truly want to start a business then I would suggest sitting down talking to an adult about what you want to do, Also it comes down to if you're selling something such as bracelets, slime, nail polish ... whatever your selling, Or if you are doing good like doing hair, Painting houses ... etc I would suggest sitting down and having an in-depth conversation.
