To find out who has the highest hourly wage, we need to calculate the hourly wage for each person by dividing their total earnings by the number of hours worked.
-
Ling: \[ \text{Hourly Wage} = \frac{108}{9} = 12 \text{ dollars per hour} \]
-
Rachel: \[ \text{Hourly Wage} = \frac{77}{7} = 11 \text{ dollars per hour} \]
-
Ruben: \[ \text{Hourly Wage} = \frac{92}{8} = 11.5 \text{ dollars per hour} \]
-
Patrick: \[ \text{Hourly Wage} = \frac{115}{10} = 11.5 \text{ dollars per hour} \]
Now let's summarize the hourly wages:
- Ling: $12
- Rachel: $11
- Ruben: $11.5
- Patrick: $11.5
The highest hourly wage is $12, earned by Ling.
