228 have registered for a sightseeing at the grand canyon. if a tour director can take 35 people on each tour,how many tour directors will be needed to accomadate everyone?
228/35 = 6.51 tour director's needed. Obviously we can't have 0.51 (a part) of a tour director so we will need 7 tour directors to accommodate all 35 people.
