I can’t see the numbers but here is a way to help you solve. Domain go from left to right and range bottom to the top
The answer is 31/35
Hope it helps!
Step-by-step explanation:
Let a be the total score of Div. A
Let b be the total score of Div. B
given,

as equation 1.
and

as equation 2.
Now multiply equation 2 by 1/20 to eliminate b to solve for a.

take this new equation as equation 3.
now we will use equation 1 + equation 3 to eliminate b to solve for a.

Div.A total score = 600
Average Score = Total Score / Number of students.
