A florist is creating 10 centerpieces for the tables at a wedding reception.Roses cost $2.50 each, lilies cost $8 each, and irises cost $4 each.The customer has a budget of $300 allocated for the centerpieces and wants each centerpiece to contain 12 flowers, with twice as many roses as the number of irises and lilies combined.
Write a system of linear equations that represents the situation.

A) $\left\{ \begin{array} { l l } 2.5 r - 8 l - 4 i & = 300 \\- r - 2 l - 2 i & = 0 \\r - l - i & = 120\end{array} \right.$
B) $\left\{ \begin{array} { l l } 2.5 r + 8 l + 4 i & = 300 \\r + 2 l + 2 i & = 0 \\r + l + i & = 120\end{array} \right.$
C) $\left\{ \begin{array} { l l } 2.5 r + 8 l + 4 i & = 300 \\- r + 2 l + 2 i & = 0 \\r + l + i & = 120\end{array} \right.$
D) $\left\{ \begin{array} { l l } 2.5 r - 8 l + 4 i & = 300 \\- r + 2 l + 2 i & = 0 \\r + l + i & = 120\end{array} \right.$
E) $\left\{ \begin{array} { l l } 2.5 r + 8 l - 4 i & = 300 \\- r + 2 l + 2 i & = 0 \\r + l + i & = 120\end{array} \right.$
