    Answer: 40

    Step-by-step explanation:

    Number of correct questions Sally got = 28 questions

    Percentage of correct questions answered = 70% on the exam,

    Total number of questions in the exam = Unknown

    Let the total questions in the exam be represented as y.

    Since Sally got 70% correctly, this will be:

    70% of y = 28

    70/100 * y = 28

    0.7 * y = 28

    0.7y = 28

    Divide both side by 0.7

    0.7y/0.7 = 28/0.7

    y = 40

    There are 40 questions in the exam.
