You can put this solution on YOUR website!

\n" ); document.write( "Remember: $\"A%2BW=40lbs\"$ -------------> EQN 1
\n" ); document.write( "Now the mixture for both w/ repective rate:
\n" ); document.write( " $\"1.60A%2B1.10W=1.25%2840lbs%29\"$ ---------> EQN 2
\n" ); document.write( "In EQN 1, we get,
\n" ); document.write( " $\"W=40-A\"$ --------------------------> EQN 3
\n" ); document.write( "Subst. EQN 3 in EQN 2:
\n" ); document.write( " $\"1.60A%2B1.10%2840-A%29=1.25%2840%29\"$
\n" ); document.write( " $\"1.60A%2B44-1.10A=50\"$
\n" ); document.write( " $\"0.50A=50-44=6\"$
\n" ); document.write( " $\"cross%280.50%29A%2Fcross%280.50%29=cross%286%2944%2Fcross%280.50%29\"$
\n" ); document.write( " $\"highlight%28A=12lbs%29\"$
\n" ); document.write( "Via EQN 3:
\n" ); document.write( " $\"W=40-12\"$ ---> $\"highlight%28W=28lbs%29\"$
\n" ); document.write( "In doubt? Go back EQN 2:
\n" ); document.write( " $\"1.60%2812%29%2B1.10%2828%29=1.25%2840%29\"$
\n" ); document.write( " $\"19.2%2B30.8=50\"$
\n" ); document.write( " $\"50=50\"$
