Word problems suck for us overthinkers Sareitha Sedai Send a noteboard - 01/04/2014 07:01:06 PM

If the question asks for the average percentage per month over some specified timeframe (in this case 4 months), you need to first calculate the monthly averages and then average them together (like you did in your first example). The question you're answering in your second method is different. It's "what is the average percentage of redheads in the room over this entire four month period" (or something like that), in which case you take the total number of redheads (4) divided by the total number of people in the room (10) and come up with 40%. The point-in-time element of this question makes it weird though

If you are from Betelgeuse, please have one of your Earth friends read what I've written before you respond. Or try concentrating harder.

If this question is from an exam, it is truly vile. Aeryn - 08/04/2014 07:14:48 AM 994 Views
You are computing two separate things. That is the problem. Tom - 01/04/2014 07:04:49 PM 695 Views
