She started out by telling us that she was going to sell 5 doughnuts for $3. Not a bad deal! That's 60 cents a doughnut, a better deal than most bakeries! Then she proceeded to tell us that she was selling 6 doughnuts for $7. Uh? Excuse me? 5 doughnuts for $3, but 6 doughnuts for $7? That's not a very good deal! That 6th doughnut cost $4 by itself!!! Then she finished up by saying that she was selling 7 doughnuts for $10. So the 7th doughnut was $3. Considering that the 6th doughnut was $4, getting the 7th for only $3 is a steal!!!
