In a local school district, the high school and middle school each received r dollars toward funding for the student arts program. The high school enrolled 300 students and the middle school enrolled 200 students. Later, the middle school transferred s dollars to the high school so that they would have received the same funding per student. Which of the following is equivalent to s?

r/2


r/3


r/4


r/5


r/6

[kmittal82]

Total money per student for high school = r/300
Money per student for middle school = r/200

Money transferred = s

Thus, total money per student high school now has = (r+s)/300
total money per student middle school has = (r-s)/200

(r+s)/300 = (r-s)/200

Solve to get s = r/5

thus, (d)
