50 in a 35mph Zone

My question involves a speeding ticket from the State of: CA

recently i recieved a ticket for going 50 in a 35 mph zone
(which i believe the speed limit was 40 and i was going 45ish)

how much will it cost for 15mph over the speed limit?

it was night/clear weather/dry road condition/and it was light traffic(almost none)

If you contact the court identified on the ticket, they'll be able to inform you of the fines including any local assessments. You may also be able to find the information, and may even be able to pay the ticket (if that's what you intend), on the court's website.
