Answer:
Find the minimum and maximum values of the objective function subject to the given constrants. Objective function: C= 2x + 3y
Constraints:
x>0
y>0
Comment: These two conditions tell you the answers are in the 1st Quadrant.
-----------------------------
x +y < 9
Graph the boundary line: y = -x+9
Solutions points are below the boundary line and in the 1st Quadrant.
