Of the students who tried out for the school play, there were 3 times as many seniors as juniors. The difference between the number of seniors
and the number of juniors was 82. Which system of equations will
determine the number of seniors, s, and the number of juniors, j, who
tried out for the school play?
A. 3s = j
s- j = 82
C. 3j = s
S- j = 82
D. 3j =
B. 3s = j
S + j = 82
S + j = 82
