Grading scale 1 has the following weights- (tests- 50% quiz- 25% homework- 15% final exam- 10%). calculate your final average if your performance in the class is as follows-test grades- {88, 84, 90, 75, 70, 81); quiz grades- {88, 67, 90, 90, 45, 99, 76, 98, 100}; homework- 90; final exam- 75

The average final score = 82.58

Step-by-step 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 =  = 81.33%

Total % marks obtained in quiz = = 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

i think the amount would be $140.62
