\n" ); document.write( "Let x=number of lbs of $2.20 meat
\n" ); document.write( "Then 50-x=number of lbs of $4.20 meat\r
\n" ); document.write( "\n" ); document.write( "cost of $2.20 meat + cost of $4.20 meat must = cost of final mixture\r
\n" ); document.write( "\n" ); document.write( "So, our equation to solve is:\r
\n" ); document.write( "\n" ); document.write( "$2.20x+$4.20(50-x)=$3.00(50) get rid of parens\r
\n" ); document.write( "\n" ); document.write( "$2.20x+$210-$4.20x=$150 subtract $210 from both sides\r
\n" ); document.write( "\n" ); document.write( "$2.20x+$210-$210-$4.20x=$150-$210 collect like terms
\n" ); document.write( "-$2.00x=-$60.00 divide both sides by -$2.00
\n" ); document.write( "x=30 lb ----------------------------------number of lbs of $2.20 meat\r
\n" ); document.write( "\n" ); document.write( "50-x=50-30=20 lb----------------------------number of lbs of $4.20 meat\r
\n" ); document.write( "\n" ); document.write( "CK
\n" ); document.write( "30($2.20)+20($4.20)=50($3.00)
\n" ); document.write( "$66.00+$84.00=$150.00
\n" ); document.write( "$150.00=$150.00\r
