\n" ); document.write( "I believe I know the answer to this problem, but I need help in understanding why this is the answer. I can get to \"by/x\" , but I don't remember why I am going through these motions. Is there a law or property that is involved in this problem?

You can put this solution on YOUR website!
The \"rate\" the apples are selling at is:
\n" ); document.write( "{ b cents ] / [ x apples ], or
\n" ); document.write( "\"+b%2Fx+\" cents/apples
\n" ); document.write( "----------------------
\n" ); document.write( "If you multiply the \"rate\" by the number of apples
\n" ); document.write( "You get the cost of that many apples, so
\n" ); document.write( "\"+%28b%2Fx%29%2Ay+\" = \"+b%2A%28+y%2Fx+%29+\"
\n" ); document.write( "------------------------
\n" ); document.write( "[ cent / apples ] x [ apples ] = [ cents ]
\n" ); document.write( "so, the dimensions make sense
\n" ); document.write( "
\n" );
