How much will a ticket cost if you are 1-19 mph over the 65 highway mph speed limit?

I just got a ticket for going 79 in a 55 and my ticket was for $160.

I want to know personally 1. how old you are, 2. what state you're in, and 3. what kind of area it was that you got a speeding ticket (be it a school zone, highway, two way street).. that would make this answer more helpful than just posting how much it costs, though I'm not saying that was a bad answer, I'm just saying about what would've helped out more.
