Suppose there were �x� students in a class who scored 100 and �y� students who scored 50. Write an algebraic expression for the mean in terms of �x� and �y�.
----------------
average = (# of points)/(# of students)
--------------------------------------------
Points: 100x
Points: 50y
# of students: x+y
-----
Mean = Average = (100x+50y)/(x+y)
