Question 991515: sam charges 20 plus 15 for every hour to tutor. bill charges 15 a hour to tutor. how many hours do they have to tutor in order to make the same amount of money? Answer by macston(5194) (Show Source):
You can put this solution on YOUR website! They will never make the same amount unless Bill tutors 1 and 1/3 more hours than Sam. After that they make the same regardless of hours (they charge the same per hour. Otherwise, we could re-write the problem as "Sam charges what Bill charges + 20. When will they make the same?" And we can easily see that they will never make the same amount, because Sam always charges 20 more and they make the same per hour otherwise.
