Let the number of reprints = \"r\"
\n" ); document.write( "Let cost = \"c\"
\n" ); document.write( "Local photo shop:
\n" ); document.write( "\"c+=+52r\" (in cents)
\n" ); document.write( "Through mail:
\n" ); document.write( "\"c+=+44r+%2B+120\"
\n" ); document.write( "When is th3e cost of the reprints through the mail less?
\n" ); document.write( "\"44r+%2B+120+%3C+52r\"
\n" ); document.write( "Subtract \"44r\" from both sides
\n" ); document.write( "\"120+%3C+8r\"
\n" ); document.write( "Divide both sides by \"8\"
\n" ); document.write( "\"15+%3C+r\"
\n" ); document.write( "Or, writing it in the other direction,
\n" ); document.write( "\"r+%3E+15\"
\n" ); document.write( "mail order is less expensive if 16 reprints are ordered
\n" ); document.write( "check:
\n" ); document.write( "what is each way for 15 reprints?
\n" ); document.write( "\"c+=+52r\"
\n" ); document.write( "\"c+=+780\"
\n" ); document.write( "and
\n" ); document.write( "\"c+=+44r+%2B+120\"
\n" ); document.write( "\"c+=+44%2A15+%2B+120\"
\n" ); document.write( "\"c+=+660+%2B+120\"
\n" ); document.write( "\"c+=+780\"
\n" ); document.write( "OK
\n" ); document.write( "Now check each way for 16 reprints
\n" ); document.write( " \n" ); document.write( "
\n" );
