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.
