\n" );
document.write( "mixing a 15% glucose solution with a 35% glucose soution
\n" );
document.write( "Let x represent the 35% solution (assigning x to more concentrated solution)
\n" );
document.write( "then (35-x) will be the amount of the 15% soluton
\n" );
document.write( ".35x + .15(35L-x) = .19*35L
\n" );
document.write( "solving for x
\n" );
document.write( ".35x + .15*35L -.15x = .19*35L
\n" );
document.write( ".20x = .04*35L
\n" );
document.write( "x = .15*35L/.20 = 7L, the amount of the 35% solution\r
\n" );
document.write( "\n" );
document.write( "checking our answer
\n" );
document.write( "28L of the 15% solution (35L - 7L)
\n" );
document.write( ".35*7 + .15*28 = 6.65 = .19*35 \n" );
