\n" ); document.write( ":
\n" ); document.write( ".89(35) = .75(w+35)
\n" ); document.write( "31.15 = .75w + 26.25
\n" ); document.write( "31.15 - 26.25 = .75w
\n" ); document.write( "4.9 = .75w
\n" ); document.write( "w = 4.9/.75
\n" ); document.write( "w = 6.533 liters of water \n" ); document.write( "
