\n" ); document.write( "pounds of a high-grade 35%
\n" ); document.write( "protein ration. How many pounds of each should he use?\r
\n" ); document.write( "\n" ); document.write( "component percent ---------------- quantity
\n" ); document.write( "Protein A 0.45 ---------------- x lbs
\n" ); document.write( "Protein B 0.2 ---------------- 2000 - x lbs
\n" ); document.write( "Mixture 0.35 ---------------- 2000
\n" ); document.write( "
\n" ); document.write( "0.45 x + 0.2 ( 2000 - x ) = 2000.00 * 0.35
\n" ); document.write( "
\n" ); document.write( "0.45 x + 400 - 0.2 x = 700.00
\n" ); document.write( "0.45 x - 0.2 x = 700 - 400
\n" ); document.write( "0.25 x = 300
\n" ); document.write( "/ 0.25
