Sum of all grades / number of students = average grade
Average grade = 80
number of students = 1514 (excluding payton)
80 * 1514 = 121120
Average grade = 81
number of students = 1515
81 * 1515 = 122715
Sum of 1515 students = 122715
Sum of 1514 students = <u>121120</u>
Difference: 1595 *Paytons grade
