SOLUTION: An engine has a 6.2 litre capacity cooling system. If the most ideal solution of antifreeze for this engine is a 57.6 % solution (a mix of 57.6 % pure antifreeze and 42.4 % water).

Question 1020888: An engine has a 6.2 litre capacity cooling system. If the most ideal solution of antifreeze for this engine is a 57.6 % solution (a mix of 57.6 % pure antifreeze and 42.4 % water). How much pure antifreeze (in litres) must be combined with a 40.4 % solution to achieve 6.2 litres of the ideal solution?
Express your answer to three significant digits.

Let = liters of pure antifreeze to be added
= liters of 40.4% solution to use
= liters of pure antifreeze in 40.4% solution
----------------------------------------------------
I can say:

1.789 liters of pure antifreeze is needed
---------------
check:

OK
Hope I got it!
