I was at a restaurant the other day, and there was a sign that said,

"Each of our omelets is made with three eggs."

When I looked at the menu, the first three omelets were:
      Cheese omelet: 7-dollars-45-cents.
      Bacon omelet: 7-dollars-70-cents.
      Bacon and cheese omelet: 8-dollars-45-cents.

What does a plain omelet cost? (Just eggs, no bacon, no cheese).
