The question in the image asks to find Crystal's hourly rate of pay, given that:

• She worked 6 hours on Tuesday, 7 hours on Wednesday, and 3 hours on Friday.
• She earned a total of $472.

To calculate her hourly rate, we first need to find the total number of hours she worked:

$\text{Total hours} = 6 \, \text{(Tuesday)} + 7 \, \text{(Wednesday)} + 3 \, \text{(Friday)} = 16 \, \text{hours}.$

The hourly rate can then be found by dividing the total amount earned by the total number of hours worked:

$\text{Hourly rate} = \frac{472}{16}.$

From the options provided, the correct expression to represent the hourly rate is $\frac{472}{16}$, which matches the first option selected in the image.
