Question

Claudia has four French exams this semester, each with a possible high score of 100 points. Claudia's scores for the first three exams are shown below:

• Exam 1: 88 points
• Exam 2: 95 points
• Exam 3: 73 points
• Exam 4: ???
What does she need to score on the fourth exam so that her average score is 84 points?

Answer 1

80 points

Explanation:

multiply 84 by 4 to find the total score she needs for all the exams combined [ 84 × 4 = 336 ]

subtract the scores of the first three exams from the total [336 - 88 - 95 - 73 = 80]
