You can put this solution on YOUR website! There are 22 more sophomores than juniors in an 8 am algebra class. If there are 70 students in this class, find the number of sophomores and the number of juniors in the class.
------------------
Equations:
s = j + 22
s + j = 70
----
Substitute for "s" and solve for "j":
j+22+j = 70
2j = 48
j = 24 (# of juniors)
s = j+ 22 = 46 (# of sophomores)
