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:

$29A+18B=181\\3A+25B=65\\4A+6B=32$

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:

$1) 3A+25B=65\\2) 4A+6B=32$

One incognita is cleared depending on the other

$2) 4A+6B=32\\4A=32-6B\\A=8-\frac{6}{4} B$

The values obtained in the second are replaced

$1) 3A+25B=65\\3(8-\frac{6}{4} B)+25B=65\\24-\frac{18}{4} B+25B=65\\B(-\frac{18}{4}+\frac{100}{4})=41\\B(\frac{82}{4})=41\\B(\frac{41}{2})=41\\B=2$

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

$A=8-\frac{6}{4} B\\A=8-\frac{12}{4}\\A=8-3\\A=5$

How to change 3 7/8 into an improper fraction

VladimirAG [237]

3 7/8

So we can use this $a \frac{b}{c} = \frac{(a \times c) + b}{c}$

So we get

$3 \frac{7}{8} = \frac{(3 \times 8) + 7}{8}$

= $\frac{24+7}{8} = \frac{31}{8}$
