Answer 1

Answer:

The correct option is B) 71%.

Step-by-step 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:

$95\times \frac{10}{100}$

$95\times \frac{1}{10}$

$9.5$

Calculate the 20% of Quizzes as shown:

$80\times \frac{20}{100}$

$8\times 2$

$16$

Calculate the 50% of Tests as shown:

$67\times \frac{50}{100}$

$67\times 0.5$

$33.5$

Calculate the 20% of Final Exam as shown:

$60\times \frac{20}{100}$

$6\times 2$

$12$

The class average of Mark is:

9.5+16+33.5+12=71

Hence the correct option is B) 71%.
