Cost of a speeding ticket: 100+5x, where x is the number of miles over the speed limit.
Example:
Going 50 on a 30 mile zone. 50-30 = 20 you were going 20 miles over the speed limit.
Your ticket will be: 100+5x = 100+5(20) = 100+100 = $200 (ouch! tickets get expensive)

b) Evaluate S(15) and interpret the meaning in the context of this problem.
a.
S(x) = 5x + 100
b.
S(15) = 5(15) + 100 = $175

You should be able to interpret b., based on equation in a.
