Let \"d\"= pounds of lemon drops to use
\n" ); document.write( "Let \"j\"= pounds of jelly beans to use
\n" ); document.write( "\"380d\"= cost of lemon drops in mixture (in cents)
\n" ); document.write( "\"240j\"= cost of jelly beans in mixture (in cents)
\n" ); document.write( "\"380d+%2B+240j+=+296\"
\n" ); document.write( "I think there is a missing piece of information, or it's
\n" ); document.write( "not really clear how many pounds of the mixture
\n" ); document.write( "they want to make. I need another equation such as:
\n" ); document.write( "\"d+%2B+j+=+1\" if they want to make 1 pound of mixture
\n" ); document.write( "Multiply both sides by \"240\"
\n" ); document.write( "\"240d+%2B+240j+=+240\"
\n" ); document.write( "Now subtract this from the other equation
\n" ); document.write( "\"380d+%2B+240j+=+296\"
\n" ); document.write( "\"-240d+-+240j+=+-240\"
\n" ); document.write( "----------------------
\n" ); document.write( "\"140d+=+56\"
\n" ); document.write( "\"d+=+.4\"
\n" ); document.write( "\"d+%2B+j+=+1\"
\n" ); document.write( "\"j+=+1+-+.4\"
\n" ); document.write( "\"j+=+.6\"
\n" ); document.write( ".4 pound of lemon drops and .6 pounds of jelly beans are needed
\n" ); document.write( "to make 1 pound of mixture.
\n" ); document.write( "Note that you could scale this up if you wanted 10 pounds of mixture
\n" ); document.write( "\"4+%2B+6+=+10\", or use any other scale factor.
\n" ); document.write( "
\n" );
