\n" ); document.write( "P=pounds of peanuts; W=pounds of walnuts
\n" ); document.write( ".
\n" ); document.write( "P+W=100lbs
\n" ); document.write( "W=100lbs-P
\n" ); document.write( ".
\n" ); document.write( "($1.43/lb)P+($2.63/lb)W=$2.39/lb(100lbs)
\n" ); document.write( "($1.43/lb)P+($2.63/lb)(100lbs-P)=$239
\n" ); document.write( "($1.43/lb)P+$263-($2.63/lb)P=$239
\n" ); document.write( "(-$1.20/lb)P=-$24
\n" ); document.write( "P=20
\n" ); document.write( "ANSWER 1: There were 20 pounds of peanuts in the mixture.
\n" ); document.write( ".
\n" ); document.write( "W=100 pounds-P=100 pounds-20 pounds=80 pounds
\n" ); document.write( "ANSWER 2: There were 80 pounds of walnuts in the mixture.
\n" ); document.write( ".
\n" ); document.write( "($1.43/lb)P+($2.63/lb)W=$2.39/lb(100lbs)
\n" ); document.write( "($1.43/lb)(20lbs)+($2.63/lb)(80lbs)=$2.39/lb(100lbs)
\n" ); document.write( "$28.60+$210.40=$239
