Soybean meal is 16% protein and cornmeal is 8% protien, how many pounds of
\n" ); document.write( "each should be mixed together in order to get 320lb mixture that is 13% protein?
\n" ); document.write( ":
\n" ); document.write( "let x = amt of soy
\n" ); document.write( "The total will be 320, therefore:
\n" ); document.write( "(320-x) = amt of corn
\n" ); document.write( ":
\n" ); document.write( ".16x + .08(320-x) = .13(320)
\n" ); document.write( ":
\n" ); document.write( ".16x + 25.6 - .08x = 41.6
\n" ); document.write( ":
\n" ); document.write( ".16x - .08x = 41.6 - 25.6
\n" ); document.write( ":
\n" ); document.write( ".08x = 16
\n" ); document.write( "x = \"16%2F.08\"
\n" ); document.write( "x = 200 lb of soy
\n" ); document.write( "then
\n" ); document.write( "320 - 200 = 120 lb of corn
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check solution:
\n" ); document.write( ".16(200) + .08(120) = .13(320)
\n" ); document.write( "32 + 9.6 = 41.6 \n" ); document.write( "
