Answer:

Julio's hourly rate is $12.80 per hour.

Step-by-step explanation:

Julio is paid 1.2 times his normal hourly rate for each hour he works over 31 hours in a week.

Let his hourly rate be r

So, when he works 41 hours, he gets paid $550.40

Equation forms :

31r+10(1.2r)=550.40

Solving for r now;

31r+12r=550.40

=> 43r=550.40

r = 12.8 dollars per hour

Hence, Julio's hourly rate is $12.80 per hour.

Let Julio's normal hour rate is $x .

So we have

31x + (41-31)*1.2 x = 550.40
\\
31x +10*1.2x = 550.40
\\
31x+12x = 550.40
\\
43x= 550.40
\\
x = \frac{550.40}{43}=$12.80

So Julio's hourly rate is $12.80.

And this is reasonable , since working 41 hours at a rate of  $ 13 per hour is

=41(10+3)=410+123=533

is close to 550.40 .
