First, find the hourly pay rate by dividing the total amount received over the working time. Since Mae receives $129.00 for working for 10 hours, then the hourly rate is:
[tex]\frac{129.00}{10}=12.90[/tex]
Next, multiply the hourly rate by the number of hours worked to find the total earnings. Since one day Mae worked 9 hours, then the total pay for that day is:
[tex]12.90\times9=116.10[/tex]
Therefore, Mae earned $116.10 that day.
