Problema Solution

An agriculture company has 80 tons of type I fertilizer and 120 tons of type II fertilizer. The company mixes these fertilizer into two products. Product X requires 2 parts of type I and 1 part of type II fertilizers. Product Y requires 1 part of type I and 3 parts of type II fertilizers. If each product sells for $2000, what is the maximum revenue and how many of each product should be made and sold to maximize revenue?

Product X requires 2 parts of type I and 1 part of type II fertilizers:


2x tones of type I fertilizer


x tones of type II fertilizer


Product Y requires 1 part of type I and 3 parts of type II fertilizers:


y tones of type I fertilizer


3y tones of type II fertilizer


An agriculture company has 80 tons of type I fertilizer and 120 tons of type II fertilizer:


2x + y <= 80


x + 3y <= 120


are the constrains.


The objective function is:


F(x , y) = 2000(x + y)

2x + y <= 80


x + 3y <= 120


the corner points are:


(40, 0), (0, 40) and (24, 32)


(24, 32) is found by solving the system of equations:


2x + y=80,


x+3y=120

F(40 , 0) = 2000*40 = $80,000


F(0,40) = 2000*40 = $80,000


F(24, 32) = 2000(24 + 32) = $112,000


the maximum revenue is $112,000.


24 Product X and 32 Product Y should be made to maximize revenue.
