Answer:
The animal farm should buy 1.775 bags of soybeans and 1.575 bags of oats

Step-by-step explanation:
The given parameters can be summarized as:

Where: x = Soybeans and y = Oats.
So, the system of equations are:




The best way to solve this, is using graph
Plot the following equations on a graph, and get the points of intersection:



From the attached graph, we have:



Substitute each of the values of x's and y's in the cost function to get the minimum cost:










The values of x and y that gives the minimum cost is:

and the minimum cost is:

Hence, the animal farm should buy 1.775 bags of soybeans and 1.575 bags of oats
