How many liters of a 30% alcohol solution must be mixed with 60 liters of 90% solution to get a 60% solution?
\n" ); document.write( "-------
\n" ); document.write( "Equation:
\n" ); document.write( "alc + alc = alc
\n" ); document.write( "0.30x + 0.90(60) = 0.60(x+60)
\n" ); document.write( "------
\n" ); document.write( "30x + 90*60 = 60x + 60*60
\n" ); document.write( "-----
\n" ); document.write( "-30x = -30*60
\n" ); document.write( "x = 60 liters (amt. of 30% solution needed)
\n" ); document.write( "---------------
