Susan C. Posted September 16, 2010 Share Posted September 16, 2010 OK, dd got this problem wrong, and the teacher key seems to have forgotton to put the set up of this problem, only the answer, its probably very simple, but that all isn't hitting my brain at the moment: What is the strength of a salt solution that contains 12 gallons of salt and 18 gallons of pure water?
