How much to pay a child pocket money

Hi everyone. I have a 11 year old girl and she does chores around the house for pocket money. She does the chores without asking and never complains. She likes to earn money and save it for a rainy shopping day. We never allow her to do more then two chores a day as i believe we all live in the house we all muck in. How much would you pay per chore? Cleaning kitching, washing up, wiping up, putting laundry on, folding up dried clothing, cleaning bathroom, cleaning floors sweeping/steaming or hoovering, tidying up in general and sometimes she does gardening. These are some of the things she chooses to do. Do you allow your child to earn pocket money by way of chores? Thanks for replies in advance.
