Jenna and her friend, Khalil, are having a contest to see who can save the most money. Jenna
has already saved $110 and every week she saves an additional $20. Khalil has already saved $80
and every week he saves an additional $25. Let x represent the number of weeks and y represent
the total amount of money saved.
So far I've got 110+20x= ??? for jenna because I don't know what goes after the equal sign and 80+25x=???
