\n" );
document.write( "There is available 60 gallons of a 50% solution of glycerin and water. What volume of water must be added 
\n" );
document.write( "to the solution to reduce the glycerin concentration to 12% (88% water)  
\n" );
document.write( "      water = water (total gallons same on both sides)
\n" );
document.write( " x + .50*60 = .88(x+60) 
\n" );
document.write( "      .22x = .33*60
\n" );
document.write( "         x = 90gal of water must be added\r
