Question

You're studying for your final exam of the semester. Up to this point, you received 3 exam scores of 80%, 82%, and 88%. To receive a grade of B in the class, you must have an average exam score between:

A) 67% to 97%
B) 62% to 100%
C) 70% to 100%
D) 62% to 100%

Answer 1

To receive a grade of B in the class, the student's average exam score must be between 70% and 100%. The average of 80%, 82%, and 88% is 83.33%, which falls within the required range.

Step-by-step explanation:

To calculate the average exam score, we add up all the scores and divide by the number of exams. In this case, the student received scores of 80%, 82%, and 88%. Adding them together gives us 250%.

Dividing by 3, the number of exams, gives us an average score of 83.33%. Since this average falls within the range of 70% to 100%, the student will receive a grade of B in the class.
