(x1 + x2 + … + x9) / 9 = 10.03 // The average of the 9 accepted students.

(x1 + x2 + … + x10) / 10 = 9.86 // The average of all 10 applicants

(x1 + x2 + … + x9) = 90.27 // The cumulative GPA of the 9 accepted students

(90.27 + x10) / 10 = 9.86 // [(x1 + … + x9) + x10] / 10 = 9.86

x10 = 8.33 // Solve for x10
