We have the expression 100*p. This means that there is 100 of something for every p (player) due to that we multiply each p by 100. We don't know what p is, so if it states, for example, that there is 100 of something in total, that would mean that 100/100=1 and p would have to be 1, which isn't correct. In addition, be realistic - for example, there wouldn't be 100 tickets for every player to a park if everyone needed one ticket to get in.
I won't give you the answer, but the explanation should give you a pretty good idea of what it is - good luck, and feel free to ask with any questions!
