I got a ticket several years ago when I was either 16/17 and it was for going 95 in a 60. I paid $250 for it, and that was after the cop wrote my ticket down to 75 in a 60. If it wasn't for that guy I would have had my license revoked and like a $1000 fine. So really I wouldn't worry too much about your ticket, on top of that a-lot of cities offer payment plans for your tickets. You just have to arrange it.
I haven't sped since that day. Most I'll go is 10 over, and that's on the freeway. 5 over in town.
