For example, a bag of vigoro ultra turf fertilizer contains 29 pounds of nitrogen, 3 pounds of phosphoric acid, and 4 pounds of potash. another type of fertilizer, parker's premium starter, has 18 pounds of nitrogen, 25 pounds of phosphoric acid, and 6 pounds of potash per bag. determine the number of bags of each type required to yield a mixture containing 181 pounds of nitrogen, 65 pounds of phosphoric acid, and 32 pounds of potash.

When we are given information on different products and are asked to calculate a result from these, we are generally being provided with equations, in this case to calculate the number of bags required to make the requested mixture we have the following equations:

Where A and B represent the number of bosas of each fertilizer brand, as we have two unknowns we will use two equations like this:

One incognita is cleared depending on the other

The values obtained in the second are replaced

With the value of B it is replaced in the first one to obtain the value of A:

Answer

5 bags of Vigoro Ultra Turf and 2 of Parker's Premium Starter are needed
