Question 1094296: A 10-quart radiator contains a 40% antifreeze solution. How much of the solution needs to be drained out and replaced with pure antifreeze in order to raise the solution to 70% antifreeze? Found 2 solutions by josmiceli, ikleyn:Answer by josmiceli(19441) (Show Source):
You can put this solution on YOUR website! Let =quarts of solution to be
drained and replaced with pure antifreeze = quarts of alcohol drained off = quarts of alcohol originally
in the radiator
----------------------------------------
-------------
5 quarts needs to be drained and replaced
with pure antifreeze
-----------------------
check:
OK
