    The student's overall grade is 85.79%

    Step-by-step explanation:

    Given in the question that:

    Exam = 50%; Quiz = 30%, Home work = 15% and Class participation = 5%

    The total giving us 100%.

    A particular student scored the following;

    87.9% on exams, 77.8% quiz, 90% Home work and 100% on class participation

    Calculating the percentages the student had for each;

    Exam total = 50*0.879 = 43.95% earned

    Quiz = 30*0.778 = 23.34% earned

    Home work = 15*0.9 = 13.5% earned

    Class participation = 5*1 = 5% earned

    Total earned = 43.95 + 23.34 + 13.5 + 5 = 85.79%
