-------------------------
Milk function:: 4u + 2n <= 16
Flour function: 3u + 3n <= 15
--------------------
Graph:: u <= -(1/2)n + 4
Graph:: u <= -n + 5
-------------------------

-------------------------
Find the point of intersection::
-(1/2)n + 4 = -n + 5
(1/2)n = 1
If n = 2; then u = 3
-----
(n,u) Vertices:: (0,4),(5,0),(2,3)
---------
Evaluate Profit at the vertices::
Profit function:: P = 2n + 3u
(0,4) gives P = 2*0 + 3*4 = 12
(5,0) gives P = 2*5 + 3*0 = 10
(2,3) gives P = 2*2 + 3*4 = 16
------
Max Profit comes with 2 banana and 3 blueberry
