The Chart Shows the Number of Personal Bankruptcy Filings in Three

The chart shows the number of personal bankruptcy filings in three City regions during various months of 2001 - 2002. $$\begin{array} { | l | l | l | l | } \hline & \text { Jan 01 } & \text { Jul 01 } & \text { Jan 02 } \\\hline \text { North } & 140 & 140 & 140 \\\hline \text { West } & 290 & 290 & 230 \\\hline \text { East } & 230 & 230 & 190 \\\hline\end{array}$$ Write a matrix product whose computation gives the total number by which bankruptcy filings in January, 2001, exceeded filings in January, 2002.

A) $\left[ \begin{array} { l l l } 0 & 1 & 1\end{array} \right] \cdot \left[ \begin{array} { l l l } 140 & 140 & 140 \\290 & 290 & 230 \\230 & 230 & 190\end{array} \right] \cdot \left[ \begin{array} { c } 1 \\1 \\- 1\end{array} \right] = [ 110 ]$
B) $\left[ \begin{array} { l l l } 1 & 1 & 1\end{array} \right] \cdot \left[ \begin{array} { l l l } 140 & 140 & 140 \\290 & 290 & 230 \\230 & 230 & 190\end{array} \right] \cdot \left[ \begin{array} { c } - 1 \\0 \\- 1\end{array} \right] = [ 90 ]$
C) $\left[ \begin{array} { l l l } 1 & 1 & 1\end{array} \right] \cdot \left[ \begin{array} { l l l } 140 & 140 & 140 \\290 & 290 & 230 \\230 & 230 & 190\end{array} \right] \cdot \left[ \begin{array} { c } 1 \\0 \\- 1\end{array} \right] = \left[ \begin{array} { c } 100\end{array} \right]$
D) $\left[ \begin{array} { l l l } 1 & 0 & - 1\end{array} \right] \cdot \left[ \begin{array} { l l l } 140 & 140 & 140 \\290 & 290 & 230 \\230 & 230 & 190\end{array} \right] \cdot \left[ \begin{array} { l } 1 \\0 \\1\end{array} \right] = [ 80 ]$
E) $\left[ \begin{array} { l l l } 1 & - 1 & 1\end{array} \right] \cdot \left[ \begin{array} { l l l } 140 & 140 & 140 \\290 & 290 & 230 \\230 & 230 & 190\end{array} \right] \cdot \left[ \begin{array} { c } 1 \\0 \\- 1\end{array} \right] = [ 130 ]$
