The answer is 112 because you have to subtract. 285 visitors (Sunday) minus 173 visitors (Friday) your answer would be 112 visitors so there were 112 visitors more visitors on Sunday than on Friday.
Well, this is very simple all you need to do is subtract 285 - 173 which equals 112 so there were 112 more people at the art show on Sunday then on Saturday.
