14% are known to be infected.

14% = 4,200 since that is the number of known infected

6 x 14 = 84 ( +/- 2)

Therefore 6 x 4,200 is the total of undetected infected

walking around? TOTAL = 25,000 ?

Have i got that right?

That's close to what my cross multiplication gives me. I come up with 30k in total.

I might be rusty though:

ratio 4200 to .14 = x to .86
4200 / .14 = x / .86
4200 x .86 = 3612
3612 / .14 = 25800 (comprises the 86% undetected)
25800 (undetected) + 4200 (detected) = 30,000 total


is that right?

>>Have i got that right?<<

No, and I can’t follow your math, but you’re not far off.

If 14% of the total infected have been confirmed, the total infected is X and confirmed cases are 4,200 (your number).

So .14 times X = 4,200 is the equation to solve for X

X = 4200 divided by .14 so X = 30,000 (Total Infected)

But the 86% number is from a model, remember, and therefore quite suspect. If only 4% of total cases have been confirmed, for example, X would be 105,000. And since we’ve just really gotten started with testing in the U.S., the number of unconfirmed cases is probably quite high relative to, say, South Korea which has been testing relentlessly for weeks now.
