    Cathy lives in a state where speeders are fined $11 for each mile per hour over the speed limit. Cathy was given a ticket for $99 for speeding on a road where the speed limit is 65 miles per hour. How fast was Cathy driving? 71 mph 79 mph 74 mph 78 mph

    Let x be the number of "speeding" miles Cathy is going. 11x <-- this is 11$ for each "speeding" mile. So if Cathy was given a $99 ticket, we could write an equation like this: 11x=99 $11 per mile equals 99 total dollars. Then let's solve for x! Hmm if the speed limit is 65, we our final step will be to add x to 65.
