Question 24 • High School Math 2 A

Nora wants to find her average grade in her science class. She has earned a score of 85% on two tests, 92% on three tests, and 94% on her most recent test. What is Nora’s mean, or average, test score?

Answer
A
89.2%
B
90%
C
90.3%
D
91%

Explanation

Nora has six test scores: two scores of 85%, three scores of 92%, and one score of 94%. Their total is (2 × 85) + (3 × 92) + 94 = 540. Dividing by the six tests gives 540 ÷ 6 = 90%, so her mean score is 90%.
