Text: Write an equation based on the following problem, solve the equation, and explain why the problem has no solution:
How mucn 30% acid should be mixed with 15 L of 50% acid to obtain a mixture that is 60% acid?
I know the described procedure can only dilute the mixture, but I tried a conventional approach to come up with an equation: .30x + .50(15) = .60(x+15). Working this results in a "5 L" answer. But because this is not possible, I'm not sure how to explain "why the problem has no solution" when it appears (5 L) that it does.
Thank you.
