Answer:
She charges $6.75 per hour
Step-by-step explanation:
If she charges an hourly rate, the number of hours should be multiplied by the hourly rate to get the total amount of money earned.
Variable x = hourly rate
The equation should be set up as:
12x = 81
This equation says 12 hours times the hourly rate equals $81
How we solve is by isolating the variable
To isolate the variable, we divide both sides by 12
12x ÷ 12 = 81 ÷ 12
1x = 6.75
x = 6.75
Her hourly rate is $6.75
