X 1, X2 > 0
Questions:
a. Plot all constraint.
b. Show algebraically how to determine the feasible side of constraint 5.
c. Determine the feasible region by shading or by arrows that indicate the feasible side.
d. Find the optimal solution either by Iso-profit or by enumeration. Answer this part in the bluebook except the plotting of the Iso-profit if you use it.
