Answer:
$9/hour
Step-by-step explanation:
The hourly rate of pay is the number of dollars per hour she gets.
Since you need dollars per hour, and that means dollars divided by hours, divide the number of dollars by the number of hours in any of the given lines.
$180/(20 hours) = $9/hour
All lines will give you the same answer.
$135/(15 hours) = $9/hour
$198/(22 hours) = $9/hour
