\n" );
document.write( "Gabe Amodeo,a nuclear physicist, needs 50 liters of a 60% acid solution. 
\n" );
document.write( "he currently has a 20% solution and a 70% solution. 
\n" );
document.write( "Let \"highlight_green%28x%29\" and \"highlight_green%2850-x%29\"represent the amount of the 70% and 20% solutions respectively
\n" );
document.write( "Question states***
\n" );
document.write( " .70x + .20(50-x) = .60*50L    |multiplying thru by 100
\n" );
document.write( "  70x + 20(50-x) = 3000L
\n" );
document.write( "       50x = 2000L
\n" );
document.write( "         x =40 L of 70% solution
\n" );
document.write( "and \"highlight_green%2850-x%29\" is 10 L of 20% solution \n" );
document.write( "
\n" );
