Business Massachusetts has a graduated fine system for speeding, meaning you can pay a base fine and then have more charges added on top. For example, the base fine for speeding is $100. But that is just the start. If you are convicted of going more than 10 mph over the speed limit, add $10 for each additional mph you were traveling over the speed limit plus 10 mph. Thus, the amount of the fine y (in dollars) for driving x miles over the speed limit (when the speed limit is 65 miles per hour) can be represented as y= 10(x− 75) + 100, x≥ 75.
