Use the Two-Stage Method to Solve A) Minimum Is 77 For

Use the two-stage method to solve.
- $$\begin{array}{ll} \text { Minimize } & w=18 x_{1}+11 x_{2} \\\text { subject to: } & 2 x_{1}+2 x_{2}=14 \\& 6 x_{1}+2 x_{2} \geq 36 \\& 2 x_{1}+4 x_{2} \leq 24 \\& x_{1} \geq 0, x_{2} \geq 0\end{array}$$

A) Minimum is 77 for $x_{1}=0, x_{2}=7$
B) Minimum is 115.5 for $x_{1}=5.5, x_{2}=1.5$
C) Minimum is 84 for $x_{1}=1, x_{2}=6$
D) Minimum is 112 for $\mathrm{x}_{1}=5, \mathrm{x}_{2}=2$
