Answer 1

The average final score = 82.58

Explanation:

we have given,

Grading Scale 1 has the following weights :-

Tests- 50% , Quiz- 25% , Homework- 15% and Final Exam- 10%

Total % marks obtained in tests =
`(88+84+90+75+70+81)/(600) *100` = 81.33%

Total % marks obtained in quiz =
`(88+67+90+90+45+99+76+98+100)/(900) * 100` = 83.66%

Home work score = 90

final exam score = 75

Now, Weight of tests grade = 50% of 81.33 = 40.665

Weight of quiz grade = 25% of 83.66 = 20.915

Weight of homework = 15% of 90 = 13.5

Weight of final exam = 10% of 75 = 7.5

So the average final score = 40.665 + 20.915 + 13.5 + 7.5 = 82.5
