Answer 1

Both.

Answer 2

Rent a business? There should be some kind of a contract which would govern the terms.

It wouldn't matter where you got the money, so yes, if you made enough, you could pay the rent with money you got from the business. But if the company went out of business or didn't have enough sales to cover the "rent", you'd still be responsible for paying what you agreed to, again depending on what the contract said.
