The Price of Eggs Puzzle

The Puzzle:

The Price of Eggs
This odd little problem in domestic arithmetic was sprung by the cook upon Mrs. Smith when she wanted to know what the grocer charged for such small eggs.

"I paid twelve cents for the lot," replied Bridget, "but I made him throw in two extra ones, because they were so little, and you see that made them cost one cent a dozen less than his first asking price!"

Tell now how many eggs she received for her twelve cents?
