How much trouble for a ticket to go to for giving liquor to a minor

Had a party I am 18, a girl 16 got too drunk and I called 911, they had to pump her stomach. I have a ticket and have to go to court. I did not give her any liquor, and when I saw she was drunk I told her to stop. but I hear I am responsible. what could the consequences be. thank you.

1,000 to 2,000 maybe 500 dollars
