Correct answers only please!

Mark has the following averages in his AMDM math class:

Homework: 95

Quiz average: 80

Test average: 67

Final Exam: 60

If the teachers weights Homework at 10%, Quizzes at 20%, Tests at 50%, and Final Exam at 20%, What is Marks class average?


A. 61%

B. 71%

C. 74%

D. 82%

Answer 1

I tried it several times and the answer I came up with was 62%

Explanation:

95 x 10% = 9.5

80 x 20% = 16

67 x 50% = 33.5

60 x 20% = 12

9.5+16+33.5+12=71

`71 / 4 = 62`

So it's 61%.

I don't think any of those answers are correct. :(

Answer 2

B. 71%

Explanation:

95 × 10% = 9.5%

80 × 20% = 16%

67 × 50% = 33.5%

61 × 20% = 12%

Total - 71%
