I have added these to your question.  I have used C as the number of cookies, and n as the number of students in the room.  Now that you know the equations, you can substitute 9n+1 for C in the second equation to get <IMG STYLE=\"max-width:80%;\" SRC=/cgi-bin/plot-formula.mpl?expression=10n+=+%289n+%2B+1%29+%2B+13 ALIGN=MIDDLE  ALT=\"10n+=+%289n+%2B+1%29+%2B+13\"   DISABLED_style= \"max-width:90%; height:auto;\" >.
