I was going through some English page with grammar where I saw their explanation to a problem when to say 'as'/'like' correctly and I have to say I was left perplexed.
The site explained to use like in case of appearance and as more as a functional property of something/someone, for example:
You act like a child.
He works as a teacher.
Plus another explanation (as .. as, look like, ...) I thought I understood it.
But a few hours later I got to a situation where I wanted to say: "Let's do it as/like a team." and I don't know which one it should be.
I went through the whole site again, then checked some other sites, but I'm only finding clues which lead to both options, so I hope someone could help me to answer my problem.
