Write a System of Equations in X and Y Describing $\$ 11$

Write a system of equations in x and y describing the situation. Do not solve the system.
-Bowie has $\$ 11$ less in his pocket than Donna has. If Donna had $\$ 5$ more, she would have 3 times as much money as Bowie.

A) $\left\{ \begin{array} { l } x = y - 11 \\ y + 5 = 3 x \end{array} \right.$
B) $\left\{ \begin{array} { l } x = y - 11 \\ y + 5 = x + 3 \end{array} \right.$
C) $\left\{ \begin{array} { l } y = x - 11 \\ y + 5 = 3 x \end{array} \right.$
D) $\left\{ \begin{array} { l } x = y - 11 \\ y - 5 = 3 x \end{array} \right.$
