Consider Paulina Jordan's following linear programming formulation:

Minimize

$$4x_1$ $$5x_2$

$1x_{1}3x_{2}90$

$8x_{1}2x_{2}160$

$3x_{1}2x_{2}108$

$1x_{2}65$

$x_1,x_{2}0$

a$)$ On tho graph on right, constraints $C_1,C_2,C_3,$ and $C_4$ have been plotted. Using the point drawing toel, plot all the comer points for the feasible area.
