    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 = 121120

    Difference: 1595 * Paytons grade
