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%

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

Step-by-step 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

So it's 61%.

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

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.
