Answer:
87 points.
Step-by-step explanation:
A student has scores of 87, 81, 96, and 79 on four quizzes.
The sum of the four scores = 87 + 81 + 96 + 79 = 343
In order to have an average of atleast 86 in five quizzes, then the student must make a total of 86 × 5 = 430
Since she has a total of 343 in the four quizzes, then she must score 430 - 343 = 87 in the fifth quiz (so that she makes an average of 86 in the five quizzes).
