Question 1189879: A chemical company mixes pure water with their premium antifreeze solution to create an inexpensive antifreeze mixture. The premium antifreeze solution contains 60% pure antifreeze. The company wants to obtain 180 gallons of a mixture that contains 40% pure antifreeze. How many gallons of water and how many gallons of the premium antifreeze solution must be mixed?

You can put this solution on YOUR website!
180 gal 0.4 antifreeze=72 gallons pure antifreeze
72 gallons pure antifreeze is contained in 120 gallons of 0.6 anti-freeze
So you want 120 gallons of antifreeze and 60 gallons of water.
