Let the normal hourly rate is

Let the overtime rate is

Number of hours he worked last week is 34 hours
The number of hours he is paid at normal rate is 31 hours
The number of hours he worked over time is 3 hours
For the 31 hours that he worked, he is paid

For the extra 3 hours that he worked, he is paid

The equation for the earnings is



Solving this equation we have

Julio hourly rate is $13.4
The hourly rate of $13 is reasonable because multiplying 13×34 = 442 which is close to $467.66
