    78.875

    Step-by-step explanation:

    the average = sum of the scores / number of scores

    average = (77 + 71 + 82+79 + 76+78+85+83) / 8

    average = 631/8 = 78.875

    To find the average add all the scores together, then divide that by the number of quizzes.

    77 + 71 + 82 + 79 + 76 + 78 + 85 + 83 = 631

    8 quizzes

    Average = 631 / 8 = 78.875 = 79
