For this one, take her hourly rate and multiply it by 1.5. 1.5 will multiply it by itself and one half in the same step.
Here is the steps to do it:
9.15 times 1.5
I just plug that into my calculator and get 13.725
Since we are talking about money, round to two decimal places, making your answer 13.73/hour, answer B or the middle one.
Hope this helps!
