\n" ); document.write( "\n" ); document.write( "I you have

gallons of 70% solution, then

gallons is pure stuff. If you have 70 gallons of 10% solution, then

gallons of pure stuff. If you mix

gallons with

gallons, you have

gallons, and 60% of this, or

is pure stuff. The amount of pure stuff has to equal the amount of pure stuff, so:\r
