For the following Linear Programming problem, which statement is true?

Max: Profit $=30*$ X$1+25*$ X$2$

Subject to:

Assembly: $2*$ X$1+5*$ X$2<=50$

Inspection: $2*$ X$1+$ X$2<=11$

Storage: X$1+$ X$2<=13$

X$1,$ X$2>=0$

X$1=4,$ X$2=4$ is a feasible solution

X$1=7,$ X$2=2$ is a feasible solution

X$1=9,$ X$2=2$ is a feasible solution

X$1=2,$ X$2=7$ is a feasible solution
