The problem in the image asks:

**"Crystal works 6 hours on Tuesday, 7 hours on Wednesday, and 3 hours on Friday. She earned a total of $472. Which expression can be used to find her hourly rate of pay?"**

To solve this, we first need to find out how many total hours Crystal worked in the week:

\[
6 + 7 + 3 = 16 \text{ hours}
\]

Next, since she earned $472, the hourly rate of pay $ r $ can be found by dividing the total amount earned by the total hours worked. The expression that represents this is:

\[
\frac{472}{16}
\]

Therefore, the correct expression is $ \frac{472}{16} $, which matches the last option shown in the image.
