-- 44% of the people surveyed preferred WWCN.
-- 22% of the people surveyed preferred WANR.
-- The difference is 22% of the people surveyed.

Strange as it may seem, "88" is not one of the choices.
Go figure !
And how come the breakdown of the answers to the survey
adds up to 103% ? Did 12 of the surveyed people have
more than one favorite ? ?
