Let S be the sum of the scores of the 14 students, excluding Peyton's score. The average score of these 14 students is 80, so the sum of their scores is 80 * 14. The average score of all 15 students, including Peyton's score, is 81, so the sum of all 15 scores is 81 * 15. Express Peyton's score as the difference between the sum of the scores of all 15 students and the sum of the scores of the 14 students excluding Peyton.
