    A) Bobby's overall grade is 70.4%

    Step-by-step explanation:

    To solve this problem we must calculate the percentages each grade represents from the overall grade. Therefore:

    assignment = 85*30% = 85*30/100 = 25.5%

    tests = 72*20% = 72*20/100 = 14.4%

    exam = 61*50% = 61*50/100 = 30.5%

    total = assignment + tests + exam

    total = 25.5 + 14.4 + 30.5 = 70.4

    Bobby's overall grade is 70.4%. Therefore the correct answer is A).
