We have that for seven and a half hours, you get 72$, then we have the following rule of three:

$\begin{gathered} 72\rightarrow7(1)/(2)hours \\ x\rightarrow1hour \end{gathered}$

then we have that:

$\begin{gathered} x=(72\cdot1)/(7(1)/(2))=(72)/((15)/(2))=(144)/(15)=9.6 \\ x=9.6 \end{gathered}$

therefore, for each hour, you get $9.6

So, for 40 hours we have:

$40\cdot9.6=384$

finally, we have that for 40 hours you get $384
