How many ounces of pure bran flakes must be added to 60 oz of cereal that is 20% bran flakes to produce a mixture that is 40% bran flakes?\r
\n" ); document.write( "\n" ); document.write( "------------------
\n" ); document.write( "Equation:
\n" ); document.write( "bran + bran = bran
\n" ); document.write( "0.20*60 + 1.00x = 0.40(60+x)
\n" ); document.write( "---
\n" ); document.write( "Multiply thru by 100 to get:
\n" ); document.write( "20*60 + 100x = 40*60 + 40x
\n" ); document.write( "60x = 20*60
\n" ); document.write( "x = 20 ounces (amt. of pure bran needed in the mixture)
\n" ); document.write( "--------------------
