B) $\left[ \begin{array} { l l l } 310,000 & 110,000\end{array} \right] + \left[ \begin{array} { l l } 9,000 & 0\end{array} \right] - \left[ \begin{array} { l l l } - 40,000 & - 40,000\end{array} \right]$

C) $\left[ \begin{array} { l l l } 310,000 & 110,000\end{array} \right] + \left[ \begin{array} { l l } 9,000 & 0\end{array} \right] + \left[ \begin{array} { l l l } - 40,000 & - 40,000\end{array} \right]$

D) $\left[ \begin{array} { l l l } 310,000 & 110,000\end{array} \right] + \left[ \begin{array} { l l } 9,000 & - 40,000\end{array} \right] + \left[ \begin{array} { l l } 0 & - 40,000\end{array} \right]$

E) $\left[ \begin{array} { l } 310,000 \\110,000\end{array} \right] + \left[ \begin{array} { c } 9,000 \\0\end{array} \right] + \left[ \begin{array} { l } 40,000 \\40,000\end{array} \right]$
