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

Thanks!!

  • Algebra - ,

    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.
