    7

    Step-by-step explanation:

    To find how many Austin got incorrect, we can start by finding how many he gets correct.

    We can express 72% as the fraction 72/100.

    Now solving we achieve, 72/100 * 25.

    By cancelling, the answer is 18. But that is how many are correct.

    We subtract 25 - 18 to reach our answer of 7.

    He would've gotten 18 right and 7 wrong since 72% of 25 is 18 and 7 would be left incorrect
