11 got a grade of 87

17 got a grade of 85

13 got a grade of 80

6 got a grade of 75

1 got a failing grade of 73

Step-by-step explanation:

Solution:

2 x 90 = 180

11 x 87 = 627

17 x 85 = 1,445

13 x 80 = 1,040

6 x 75 = 450

1 x 73 = 73

Total: 3,815

Computation:

2 x 90 = 180

11 x 87 = 627

17 x 85 = 1,445

13 x 80 = 1,040

6 x 75 = 450

1 x 73 = 73

180+627+1,445+1,040+450+73 = 3,815
