Getting my teenager to contribute to the bills!

[Nuts12]

My 16 nearly 17 year old has recently got a job with a good national supermarket and is now earning about £400 per month. She's still at college but I'd like her to contribute something to the cost of the running about we do for her taking to/from college, her friends houses, to/from work etc. I asked her yesterday for a nominal £10 to help pay for the petrol and got a hostile response! She seems to think that "her" money is for her to spend as she pleases. I really want her to learn the basics of having to budget and start contributing but she doesn't seem to have any desire to pay anything at all. By the way she's had two holidays paid for this year, and I buy most of her clothes, toiletries etc. too. Am I being unreasonable? What tactics do I need to get her buy in?

My DD is slightly older than yours - has been lucky to get a really good job and earns 3 times as much as your DD. She gives me £300 a month which is paid by standing order from her account to mine - she's not overly happy about it, but accepts it.

I don't buy her clothes, but I do taxi her around some evenings and buy her food and toilettries and pay all the household bills.
