$$\large \begin{array}{ccllll} \&hours \\\hline\\ 330&6\\ x&9 \end{array}\implies \cfrac{330}{x}=\cfrac{6}{9}$$

You can make a ratio $\frac{ 330 }{ x } = \frac{6 }{ 9 }$

you want to know how much he charges for 9 hours all you have to do is multiply the number of hours by how much is charged per hour and you will have your answer!
