You can put this solution on YOUR website!
Let x=amount of regular 10% milk needed
\n" ); document.write( "Then 80-x=amount of non-fat milk needed
\n" ); document.write( "Now we know that the amount of fat in the regular milk (0.10x) plus the amount of fat in the nonfat milk (0) has to equal the amount of fat in the final mixture (0.03*80). So our equation to solve is:
\n" ); document.write( "0.10x=0.03*80 or
\n" ); document.write( "0.10x=2.4
\n" ); document.write( "x=24 pounds------amount of regular milk needed
\n" ); document.write( "80-x=80-24=56 pounds ----amount of non-fat milk needed\r
\n" ); document.write( "\n" ); document.write( "CK
\n" ); document.write( "24*0.10=0.03*80
\n" ); document.write( "2.4=2.4\r
