A chemist wants to make a 10% solution of fertilizer. He will mix a 5% solution and a 30% solution to get 30 L of a 10% solution? How much of the 30% solution will he need? (Hint: Look at Mixture Problems Resource)

points

Step-by-step explanation:

the solution is x=1

step-by-step explanation:

we are given our   equation as

let's assume

left side function is

right side function is

now, we can draw graph

and then we can get intersection point

the intersection point will be solution

so, the solution is

x=1
