    His overall grade is 87

    Step-by-step explanation:

    This grade is a weighed average.

    The student got 88 on the homework. The homework is 50% of the grade.

    The student got 80 on the midterm exam, that is 20% of the grade.

    The student got 90 on the final exam, that is 30% of the grade.

    His overall grade is:

    G = 0.5*88 + 0.2*80 + 0.3*90 = 87

    His overall grade is 87
