316-100 equals hours -1
216/18 equals hours = 12
plus the first hour = 13 total hours on that job, and if you can find a plumber that works for 18/hr you better keep him.

$100 for the first hour leaves $216 for the rest of the time worked. Divide $216 by $18/hour and you get 12 hours. So the total time worked is 13 hours.
