These are both violations so it's not a criminal record, a lot times you can go to the court clerk a week before and take care of them then,maybe 2 weeks if your lucky . The open container is a 25 dollar fine and the other is probably 25-50 dollars. They might offer to give you an acd on at least one them,which would dismiss it in 6 months if you stay out of trouble. Plead not guilty and see if you can speak to a legal aid quickly and get an acd for the underage one and pay 25 dollars for the open container. It's your choice but the fines are under 100 dollars,Idk if a lawyer is worth it. They probably will cost at least 500 and these are violations. Make sure to go to court early because the line can be really long just to get inside the court.
I got an open container ticket and saw a person charged with the same two tickets as you. They got the underage one dismissed if they stayed out of trouble for 6 months and paid the other one.
