Question

In this class, tests and quizzes are worth 75% of your grade, while homework and classwork are worth only 25% of your grade. Use this fact to answer the following questions. If Deklynn scores an average of 70% on her tests and quizzes but has all (100%) of her homework turned in, what would be her overall grade in the class?

A. 70%
B. 72.5%
C. 75%
D. 77.5%

Answer 1

Deklynn's overall grade is calculated by taking the weighted average of her test and quiz scores and her homework completion. Her weighted score for tests and quizzes is 52.5% and for homework is 25%, adding up to an overall grade of 77.5%.

Step-by-step explanation:

To calculate Deklynn's overall grade in the class, we need to consider both the weight of the tests and quizzes and the weight of the homework and classwork. Tests and quizzes are worth 75% of the grade, and homework and classwork are worth 25%.

First, we calculate the weighted score for tests and quizzes: 70% (average score) × 75% (weight) = 52.5%.

Next, we calculate the weighted score for homework and classwork: 100% (homework completion) × 25% (weight) = 25%.

We then add both weighted scores to find the overall grade: 52.5% + 25% = 77.5%.

So, Deklynn's overall grade in the class would be 77.5%, which corresponds to option D.
