At the 2016 convention for Aim Far Motivational Society (AFMS), each AFMS member had the option of inviting just one non-member guest. Attending as the single guest of a member is the only way a non-member would be able to attend the convention. At the 2016 convention, of the AFMS Convention Hall’s seats, 60% were occupied by AFMS members, and 10% were occupied by non-member guests. How many seats does the AFMS Convention Hall have?
(1) If 60% of the members who didn’t bring a guest instead had brought one, then the hall would have been 100% full.
(2) The number of empty seats was half the number of the AFMS members present.
