Answer 1

r = Julio's hourly rate

1.4 * r = Julios over 30 hours rate.

last week he worked 30 hours at regular rate, 30r, and 5 extra hours at 1.4r, we happen to know all that is really $436.60.

`\bf 436.6=\stackrel{\stackrel{\textit{30 hours}}{\textit{regular rate}}}{30r}+\stackrel{\stackrel{\textit{5 hours}}{\textit{overtime rate}}}{5(1.4r)}\implies 436=30r+7r\\\\\\436.6=37r\implies \cfrac{436.6}{7}=r\implies 62.37148571\approx r`
