    Answer: 20 questions

    Step-by-step explanation:

    From the question, Noah is taking an online survey and after answering 16 questions, he gets a message that he has completed 80% of the survey.

    To get the total number of questions in the survey goes thus:

    Let the total number of questions be y.

    80% of y = 16

    80/100 * y = 16

    0.8 * y = 16

    0.8y = 16

    Divide both side by 0.8

    y = 16/0.8

    y = 20

    The survey has 20 questions.
