Question

Jenna is a 6th grader at CMS. Jenna was told her mean score on social studies quizzes was 94. She remembered getting scores of 97, 88, 90, and 95, but she knew she had taken 5 quizzes. What was her fifth quiz score?

Answer 1

Answer: 100

Explanation:

Since she had a mean score of 94 in her 5 tests, then the total score will be:

= 94 × 5

= 470

Since she She remembered getting scores of 97, 88, 90, and 95, for 4 quizzes out of 5 quizzes, the total of the four quizzes will be:

= 97 + 88 + 90 + 95

= 370

Then, her 5th quiz will be:

= 470 - 370

= 100
