Question

9 students in a group found that their mean score was 86 for the first math test. On the next test, each student in the group scored 7 points higher than on the first text. What was their mean score for the two tests?

Any help would be appreciated.

Answer 1

9 * 86 = 774

9 * 93 = 837

(837 + 774)/18 = ?
