Answer
$W(h)=\begin{cases}
14h,0\lt h\leq 36\\
21(h-36)+504,h\gt 40
\end{cases}$
Work Step by Step
We are given the function for a regular week of 40 hours:
$W(h)=\begin{cases}
14h,0\lt h\leq 40\\
21(h-40)+560,h\gt 40
\end{cases}$
When the number of hours diminishes to 36, the new function is:
$W(h)=\begin{cases}
14h,0\lt h\leq 36\\
21(h-36)+36(14),h\gt 40
\end{cases}$
$W(h)=\begin{cases}
14h,0\lt h\leq 36\\
21(h-36)+504,h\gt 40
\end{cases}$
