Okay dso if she got 15 points for 12 days then you would multiply them (or just add 15+15+15+15 and so on but multiplying is easier) then you are going to add 55 because of the thirteenth day.

180+55=235 is how many you have.
now you are going to subtract 500 from that number to see how many more you need. :)
