How much pure dye must be added to 4 gal of a 25% dye solution to increase the solution to 40% ?
\n" ); document.write( "----------------------
\n" ); document.write( "Equation:
\n" ); document.write( "dye + dye = dye
\n" ); document.write( "0.25*4 + x = 0.40(4+x)
\n" ); document.write( "1 + x = 1.6 + 0.4x
\n" ); document.write( "0.6 = 0.6x
\n" ); document.write( "x = 1 gal (amt. of 100% dye that must be added)
\n" ); document.write( "=========================================================
