    Answer: 68 questions

    Step-by-step explanation:

    Given dа ta:

    Exam questions = 75

    Percentage needed by Mary for the quarter = 90%

    = exam questions x percentage needed / 100

    = 75 * 90 / 100

    = 6570 / 100

    = 67.5

    Approximately Mary needs to answer 68 questions correctly to score an A for the quarter
