86.75

Divide the total number of points by the total number of points.

#=># 99+81+86+81=347

added 4 numbers #=># #347/4=86.75#

To find the student's average, you add up all the grades and then divide by the total number of quizzes.

(Average = \frac{99 + 81 + 86 + 81}{4})

(Average = \frac{347}{4})

(Average = 86.75)

So, the student's average grade is 86.75.
