Dry Boat Works Wholesales Aluminum Boats for $500 and Fiberglass $\left\{ \begin{array} { c } 500 x + 300 y < 1,500 \\500 x + 300 y > 750\end{array} \right.$

Dry Boat Works wholesales aluminum boats for $500 and fiberglass boats for $300. Northland Marina wants to order at least $750 worth but no more than $1,500 worth of boats. Write a system of linear inequalities which describes all possible combinations of aluminum boats ( x ) and fiberglass boats ( y ) that can be ordered, graph the system of inequalities, and determine whether the ordered pairs satisfy the inequality.

A) $\left\{ \begin{array} { c } 500 x + 300 y < 1,500 \\500 x + 300 y > 750\end{array} \right.$ $( 1,2 ) , ( 10,5 )$
B) $\left\{ \begin{array} { c } 500 x + 300 y \leq 1,500 \\500 x + 300 y \leq 750\end{array} \right.$ $( 10,5 ) , ( 3,0 )$
C) $\left\{ \begin{array} { c } 500 x + 300 y \leq 1,500 \\500 x + 300 y \geq 750\end{array} \right.$ $( 1,2 ) , ( 3,0 )$
D) $\left\{ \begin{array} { c } 500 x + 300 y > 1,500 \\500 x + 300 y < 750\end{array} \right.$ $( 5,0 ) , ( 1,2 )$
E) $\left\{ \begin{array} { c } 500 x + 300 y \geq 1,500 \\500 x + 300 y \leq 750\end{array} \right.$ $( 6,9 ) , ( 5,0 )$
