We can multiply 35 by 85 to get the total score of all the freshmen:
We can multiply 15 by 75 to get the total score of all the sophomores:
We can add both totals together to get the total score for all 50 students:
Now we can divide 4100 by 50 to get the average for all 50 students:
So the average for all students who took the test is 82.
