Explanation:

Consider the provided information.

Mark has the following averages in his AMDM math class:

Homework: 95

Quiz average: 80

Test average: 67

Final Exam: 60

The teachers weights Homework at 10%, Quizzes at 20%, Tests at 50%, and Final Exam at 20%,

First calculate the 10% of home work as shown:

`95* (10)/(100)`

`95* (1)/(10)`

`9.5`

Calculate the 20% of Quizzes as shown:

`80* (20)/(100)`

`8* 2`

`16`

Calculate the 50% of Tests as shown:

`67* (50)/(100)`

`67* 0.5`

`33.5`

Calculate the 20% of Final Exam as shown:

`60* (20)/(100)`

`6* 2`

`12`

The class average of Mark is:

9.5+16+33.5+12=71

Hence the correct option is B) 71%.
