    She got 5 incorrect.

    Step-by-step explanation:

    In order to find this, we start by using the formula for percentage.

    Correct/Total = Percentage

    Now we put in known quantities.

    Correct/25 =.8

    Now to solve we multiply both sides by 25

    Correct = 20

    Since she got 20 correct, we know she got 5 incorrect
