Homework Statement
A lab has a 20% acid solution and a 50% acid solution. How many liters of each are required to obtain 600 liters of a 30% acid solution?
Homework Equations
The Attempt at a Solution
.20x + .50(600 - x) = .30(600)
.20x + 300 - .50x = 180
-0.3x + 300 = 180
- 300 -300
-0.3x = -120
----- -----
-0.3 -0.3
x = 400 liters
I am sure that the answer is wrong. Can anyone tell what I am doing wrong, or how to set the problem up properly?
Thank you
