Question 17662: A car radiator holds 24 L of a 20% antifreeze solution. How much of the 20% solution should be drained and be replaced with pure antifreeze to give a 40% antifreeze solution? Answer by rapaljer(4671) (Show Source):
You can put this solution on YOUR website! Begin with 24 L of .20 antifreeze
Drain x L of .20 antifreeze
Add x L of 1.00 antifreeze
Equals 24 L. of .40 antifreeze
