Thanks!

Does anyone know how to solve this problem? Having a lot of trouble... "In a certain dormitory, each person is either a hockey fan or a football fan but not both. On Friday, the ratio of hockey fans to football fans was 2 to 3. However, on Saturday, 18 of the football fans switched and became hockey fans, and the ratio of hockey fans to football fans became 5 to 3. How many people are in the dorm?"
