A tank contains 8000L of a solution that is 40%acid. How much water should be
\n" ); document.write( "added to make a solution that is 30% acid?
\n" ); document.write( ".
\n" ); document.write( "Let x = amount (liters) of water to add
\n" ); document.write( "then
\n" ); document.write( ".40(8000) = .30(8000+x)
\n" ); document.write( "3200 = 2400+.30x
\n" ); document.write( "800 = .30x
\n" ); document.write( "2666.67 liters = x\r
