Question: 3 Solve Question: Consider this Linear Programming (LP) formulation:

\[\begin{aligned} & \text{Minimize Cost}=x+2y \\ & \text{subject to }x+3y\ge 90 \\ & \,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,8x+2y\ge 160 \\ & \,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,3x+2y\ge 120 \\ & \,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,y\le 70 \\ & \,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,x,y\ge 0 \\ \end{aligned}\]

Graphically illustrate the feasible region and apply the isocost (isoprofit) line procedure to indicate which corner point produces the optimal solution. What is the cost of this solution?
