Respuesta :

Given:

Sarvi is creating an acid solution.

He has 5 liters of a 4% acid solution

He wants to create a 7% acid solution by adding in a 9% solution.

We will find How of the 9% solution should he add in.

Let the number of liters should be added = x

The total liters of the 7% acid solution = 5 + x

So, we can write the following equation

[tex]0.04(5)+0.09(x)=0.07(5+x)[/tex]

So, the answer will be option 3
