The employer charges $22 for 2 hours, resulting in a unit rate of $11 per hour. Therefore, she charges $55 for 5 hours, calculated by multiplying the unit rate by the number of hours.
To determine how much the employer charges for 5 hours, you can set up a ratio with the payment and hours:

Now, find the unit rate (rate per hour) by dividing the payment by the hours for the known situation:
![\[\text{Unit Rate} = \frac{\$22}{2 \text{ hours}} = \$11/\text{hour}\]](https://img.qammunity.org/2016/formulas/mathematics/middle-school/1i84y6i3510w81hg5gwfi16d2f4cfm75gh.png)
Now, use the unit rate to find the payment for 5 hours:
![\[\text{Payment for 5 hours} = \text{Unit Rate} * \text{Number of Hours} = \$11/\text{hour} * 5 \text{ hours} = \$55\]](https://img.qammunity.org/2016/formulas/mathematics/middle-school/wb3gapddj9bvc95iw7yxx5art9yli4urqd.png)
Therefore, the employer charges $55 for 5 hours.
