I don't understand how to do it, you don't need to be mean about it. I am asking for someone else's help.

A) Find intensity by using B= 10 X log (I/10^-12) formula
B) Take the answer for A multiply it by the number that it gives you for the new amount of cars that pass. Divide that number by your 172.
