Soybean meal is 14% protein, cornmeal is 7% protein. How many pounds of each should be mixed together to get a 280 pound mixture that is 8% protein\r
\n" ); document.write( "\n" ); document.write( "percent ---------------- quantity
\n" ); document.write( "Soyabean 14----------------x
\n" ); document.write( "Corn 7----------------280-x
\n" ); document.write( "Total 8.00%---------------- 280 \r
\n" ); document.write( "\n" ); document.write( "14x+7(280-x)=8* 280
\n" ); document.write( "14x+1960 -7x=2240
\n" ); document.write( "14x-7x= 2240-1960
\n" ); document.write( "7x=280
\n" ); document.write( "/7
\n" ); document.write( "x=40 soyabean pounds
\n" ); document.write( "corn = 280 -40 = 240 pounds
