Borrowing money.

Isaiah's mom has borrowed $370 from his secret stash of tips from work.  What interest rate should he use so that when she pays him back in a month she gives him $400?


Work out problem and type answer in the comments.


Anyone else's mom owe them money?
My mom owes me $100, and keeps conveniently forgetting about it.
