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

Answer:

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.
