Nick has two cans of white paint, one with a 2% yellow pigment and the other with a 5% yellow pigment.
\n" ); document.write( "Nick wants to mix the two paints to get paint with a 4% yellow pigment.
\n" ); document.write( "How much of the 5% yellow pigment paint should be mixed with 0.4 gallons of the 2% yellow pigment paint to get the desired paint?
\n" ); document.write( "------------------------
\n" ); document.write( "Amt. of 5% paint = x ; Amt. of yellow = 0.05x gallons
\n" ); document.write( "----------------------------
\n" ); document.write( "Amt. of 2% paint = 0.4 gals : Amt. of yellow = 0.02*0.4 = 0.008 gals
\n" ); document.write( "----------------------------------
\n" ); document.write( "EQUATION:
\n" ); document.write( "yellow + yellow = yellow
\n" ); document.write( "0.05x + 0.008 = 0.04(x+.4)
\n" ); document.write( "50x + 8 = 40x + 16
\n" ); document.write( "10x = 8
\n" ); document.write( "x = 0.8 gallons (Amount of 5% point that must be added)
\n" ); document.write( "====================================================
