Do you like this question better? My daughter sent it to me a couple of weeks ago. She couldn’t figure it out. It’s fifth grade math.

180

Crap, I've had enough math through my years that if I didn't get it, I'd get checked for early onset dementia.

Yes, you are correct, but any good teacher will subtract a few points for not showing the work. So, for the rest out there:

5/8 went for blue, leaving 3/8 for something else. 5/9 of that 3/8 went for green, leaving (4/9) x (3/8) = 0.1666666... (or 1/6) for the remainder,who went red. That 48 is 1/6 of 288, and the original 5/8 of 288 went blue, or 180.

Nice work, Susie and Top Water! A couple of beers, or 4, or 8 or 16 or...are available for collection on my porch in June.

So like the folding paper--if the virus doubles 2 or 4 or 10 times, the whole thing will be seen as overblown--as Major and others have opined. But if it keeps doubling, we're really screwed, and we will have wished we did even more to slow the spread.

This is a whole lot more fun than talking about the coronavirus.

Then start a thread about it.

Hijacking this thread is poor form.
