Question

In order to avoid heavy traffic, Antonio can drive home after working less than 7 hours or after working more than 9 hours. How can this be written as a single compound inequality?

7 < h < 9
7 > h > 9
h < 7 or h > 9
h > 7 or h < 9

To express the conditions under which Antonio can drive home to avoid heavy traffic as a single compound inequality, we need to look at the two scenarios provided:

1. He can leave after working less than 7 hours: \( h < 7 \)
2. He can leave after working more than 9 hours: \( h > 9 \)

These conditions can be combined using "or" since either condition allows him to avoid heavy traffic. Therefore, the correct way to write this as a single compound inequality is:

**\( h < 7 \) or \( h > 9 \)**

So, the correct answer is:

**h < 7 or h > 9**
