Jackson spends 9 hours playing video games and 1/3 that much time studying. If Jackson's grade starts at 0 points and increases by 15 points for every hour he spends studying, what is his grade?
How many hours does Jackson spend studying? ** First find how many hours he spends studying by dividing the number of hours spent gaming by 3: 9 hours / 3 = <<9/3=3>>3 hours.
How many points does Jackson earn for studying? ** Then multiply that quantity by the point increase per hour to find Jackson's grade: 3 hours * 15 points/hour = <<3*15=45>>45 points.
