    It's 60.

    Step-by-step explanation:

    You can think of it like this:

    If Jackson got a grade of 5% for 3 questions, then I can continuously multiply by 3 to get to 100.

    3 questions is 5%.

    6 questions is 10%.

    12 questions is 20%.

    24 questions is 40%.

    48 questions is 80%.

    Add another 12 questions for another 20%, and you get 100%.

    48 + 12 is 60. 60 is your answer.

    I put it this way so that way you can understand the basic concept of percentages.
