In words:
\n" ); document.write( "[ price / weight ] x [ weight of product bought ] = [ price paid for product bought ]
\n" ); document.write( "-----------------------
\n" ); document.write( "Say 100 pounds of yogurt is bought
\n" ); document.write( "price paid = $\"+%28+1.6+%2F+%28%281%2F4%29+%29%29%2A100+\"$
\n" ); document.write( "---------------------------------
\n" ); document.write( "The way to deal with $\"+1.6%2F%28%281%2F4%29%29+\"$ is
\n" ); document.write( "multiply top and bottom by $\"+4+\"$
\n" ); document.write( " $\"+1.6+%2F+%28%281%2F4%29%29+=+6.4+%2F+1+\"$ , so
\n" ); document.write( " $\"+%28+1.6+%2F+%28%281%2F4%29%29+%29%2A100+=+6.4%2A100+\"$
\n" ); document.write( " $\"+6.4%2A100+=+640+\"$
\n" ); document.write( "$640 is paid for 100 pounds of yogurt
\n" ); document.write( "-----------------------------------
\n" ); document.write( "Instead of 100 pounds, use whatever weight you want
\n" ); document.write( " \n" ); document.write( "

\n" );
