Find the production matrix for the following input-output and demand matrices using the open model.
$A=\left[\begin{array}{cc}-0.1& 0.2\\ 0.55& 0.4\end{array}\right]$
$D=\left[\begin{array}{c}3\\ 4\end{array}\right]$

$A=\left[\begin{array}{cc}-0.1& 0.2\\ 0.55& 0.4\end{array}\right]$
$D=\left[\begin{array}{c}3\\ 4\end{array}\right]$
The production matrix is $=\left[\begin{array}{c}-0.3+0.8\\ 1.65+1.6\end{array}\right]$
$=\left[\begin{array}{c}0.5\\ 3.25\end{array}\right]$

$A=\left[\begin{array}{cc}-0.1& 0.2\\ 0.55& 0.4\end{array}\right]\ast \left[\begin{array}{c}3\\ 4\end{array}\right]=\left[\begin{array}{c}\left(-0.1\right)\ast \left(3\right)+\left(0.2\right)\ast \left(4\right)\\ \left(0.55\right)\ast \left(3\right)+\left(0.4\right)\left(4\right)\end{array}\right]=\left[\begin{array}{c}0.5\\ 3.25\end{array}\right]$
