L&C financial aid

I got 22k in aid and 2.7k in loans. This is far too expensive for me, so I don’t plan on attending. However, I have a friend whose family makes significantly more money than mine, but she got 2k more in aid than me and much better loans. How much of the aid merit? Her GPA is slightly better than mine, but my test scores and ECs are superior. Should I contact the financial aid office about this? It doesn’t make sense that she should get more aid than me, when our applications are nearly identical and she has far more money than me.
