Before the final exam, a student has test scores of 72, 80, 65, 78, and 60. If the final exam counts as onethird of the final grade, what score must the student receive in order to have a final average of 76 percent?
Thanks!!

Test Average = (72+80+65+78+60)/5 = 71
Test Points = 2/3 * 71 = 47.33
47.33 + S/3 = 76
142 + S = 228
S = 86 = Final Exam score.
