just follow your heart to what you feel is well worth it. Depends on how your sales were, how busy and how much she helped. I have had help few times, and in my experiences. sometime there'll be hardly money made, and for you to say oh i'll pay you $50 bucks and you didn't even make that, then you just lost more money. 2nd....what if this person sat the whole time while you're sweating your butt off working. *had that happened to me* lol soo that's my experience, I would just say, let's see how this show goes. and follow your heart....it might be full of joy that you'll be generous.
