Answer:
54-9t
Step-by-step explanation:
multiply the 9 with 6 and multiply 9 with the t which has an invisible 1
Shouldnt it be like 150 idk
6^{2} this represents 6 with a power of 2 on the keyboard
First lets remove the initial fee

150 is how much she is charging you per hour.
If each hour is 55, lets divide 150 by 55.

She charged you for 2.7 hours (almost 3) of service
