Make money. The profit of a mutton skewer is about one piece, while the profit of a sesame seed cake is less than 50 cents, and the total cost does not exceed 1 block 5. However, the selling price of a mutton skewer with sesame seed cake by Wu Xuechang is more than 5 pieces, and the net profit is only 3.5 pieces.
