1. The problem statement, all variables and given/known data A newspaper reported an attendance of 15,000. If you assume that this number contains two significant figures, how many people could actually have been at the game? 3. The attempt at a solution I'm having difficulty answering this problem not because I don't know how to use significant figures, but why we use significant figures. My prof says that since 15000 can be represented as [tex]1.5 x 10^4[/tex] the number of people in attendance would range from [tex]1.4 x 10^4[/tex] to [tex]1.6 x 10^4[/tex]. Could someone please explain this to me?
