Poll: Operating profits have increased twofold.
Operating profits have increased twofold.
twofold = doubled = 100%
it's a little scary that so many people have this wrong
I agree that you're right, Rick, but someone could take it as an *increase* of double the amount, which would be a 200% increase and a final result of 300% of the original. If you fold a piece of paper twice (two folds), you now have 3 sections instead of 1 :)
