\n" ); document.write( "Tutor @mananth has provided a good standard formal algebraic solution. You can use that as a good example of how the problem can be solved.

\n" ); document.write( "Or, if you like to torture yourself, you can also use the rather absurd method tutor @josgarthmetic loves to show on this kind of problem -- with all those variables.

\n" ); document.write( "Finally, if a formal algebraic solution is not required, this problem can be solved in a few seconds informally:

\n" ); document.write( "The target of 60% is 3/4 of the way from 30% to 70%; therefore, 3/4 of the mixture is the 70% fruit juice.

\n" ); document.write( "ANSWER: 3/4 of 80 pints, or 60 pints, is the 70% fruit juice; the other 20 pints is the 30% fruit juice.
