\n" ); document.write( ":
\n" ); document.write( "Let x = amt of 90% solution. Then water = (30-x); (Water is a 0% solution:)
\n" ); document.write( ":
\n" ); document.write( "The percent equation, the water is out of it of course, but maybe it will make
\n" ); document.write( "it more understandable:
\n" ); document.write( ":
\n" ); document.write( "0(30-x) + .9x = .15(30)
\n" ); document.write( ":
\n" ); document.write( "0 + .9x = 4.5
\n" ); document.write( "x = 4.5/.9
\n" ); document.write( "x = 5 liters of the 90% stuff;
