Sinterklaas spends almost all his money on the good children of 3 HAVO at Adelbert College. He hardly has any money left to keep himself alive. That is why he eats gingerbread cookies every day, because they are super cheap. He has just enough money left to eat a hair salon once a week (which is three times the price). One day the price of gingerbread cookies increases by a few percent. You know that an increase in the price normally leads to a decrease in demand, but in the case of Saint Nicholas this is the other way around. He is going to eat more gingerbread cookies, from the moment of the price increase every day of the week. Provide an explanation for this
