In the tea shop, Jiugong and Meng Yao reported today's profitability.

After Meng Yao left, she returned to the little lady's house, and everyone began to count, and three stones of flour were made into fritters, which were sold for a total of 661 yuan. If calculated according to the current 150 wen yuan per stone in the grain store, the cost of three stone flour is 450 wen, the cost of other oilseeds, alum and other materials is 70 wen, and the cost of making zuò bean curd is 90 wen, the total cost is 610 wen, and the actual profit is 51 wen.

If according to the agreement with Meng Yao, the price of flour and other materials is halved and sold to Wang Dong, then the total cost will be reduced to about 350 Wen, the profit will be 311 Wen, and the profit will be eighty percent of the subsidized price of flour and other materials, then Meng Yao will get a total of about 580 Wen, and Meng Yao's profit is far from doubling the profit promised by Wang Dong.

One stone of flour, if you want to double the profit, Meng Yao needs to get at least 230 yuan, three stones of flour, it is 690 yuan, plus the cost of soybeans, according to Wang Dong's promise, she should get about 780 yuan.

But now, between 580 and 780, there is a lot of difference.

This matter has always been dominated by Wang Dong, and at this moment, when he told the results of his calculations to Sù Jiugong and others, everyone was disappointed.

After a busy morning, I didn't expect it and expected, but it was much worse.

Jiugong sighed, looked at Wang Dong, and said, "There is too much difference between 580 Wen and 780 Wen, it seems that your method will not work." ”

Wang Dong said: "Yes, it seems that it is still a little difficult to double the profit. ”

What went wrong? The difference between theory and practice is so huge.

The theory is correct, but the amount of money sold is wrong, so ...... The problem must be in the process of implementation.

In the dreary atmosphere, everyone was a little depressed, only Wang Dong, who was thinking about all the processes in the morning.

"How can we increase the money from the sale?" Wang Dong's gaze couldn't help but fall on a few remaining fritters.

At this moment, it is already afternoon, and the remaining fritters are no longer as straight as they were in the morning, they are actually lying on the plate softly, Wang Dong uses chopsticks to pick up the fritters, the fritters are soft, and from time to time there are drops of soybean oil dripping, and when you bite it, there is no sweetness when you just come out of the pot, and then look at the inside of this fritters, it is not completely exploded.

Seeing this, Wang Dong's eyes couldn't help but light up: "It turns out that the problem is here." ”

Turning around, Wang Dong excitedly said to Jiugong and the others: "Come and see, what's so strange about this fritters?" ”

Jiugong and the little lady came to Wang Dong, looked at the fritters in his hand, and said, "It's been a long time, of course it's like this." ”

Wang Dong shook his head: "No, the reason why the fritters are like this after they are cooled is because the dough has not completely exploded." ”

"What do you mean?" The crowd was puzzled.

Wang Dong said: "It's very simple, we still have problems with the dough we make. ”

"Huh?"

Everyone didn't know what kind of effect Wang Dong wanted, but seeing that he was so sure, they began to study the dough again with him.

Regardless of resting, one afternoon, Wang Dong, Jiugong and others were busy experimenting, and finally, when the lady of the Zhang family began to make noodles with warm water, a strange phenomenon occurred.

The dough fried with the dough of the Zhang family lady and the dough of the same size was actually larger than before, and the length was also increased by one-third.

Seeing this, Wang Dong couldn't help but be overjoyed, hugged the Zhang family's lady, and said excitedly: "It's successful, it's successful, we've finally succeeded!" Thank you! ”

Wang Dong couldn't help but be excited, because now, the fritter in front of him, except for the size, was almost exactly the same as what he had eaten in the 21st century.

"It turns out that because the warm water can make the yeast fully function, the fried fritters will be more fluffy."

Wang Dong was excited alone, but the others were at a loss, and Jiugong asked, "In this way, you can double your profits?" ”

Wang Dong suppressed the excitement in his heart, nodded and said: "Jiugong, you see, the same piece of dough can make one-third more fritters, that is to say, if you use such dough to fry the same size as the morning, you will use one-third less dough." ”

When Wang Dong's words came to this, no matter how stupid a person was, he already understood what he meant.

The lady of the Zhang family calculated with her eyes shining: "That is to say, the fritters made of three stones of flour will be thirty percent more, and the money sold will also be thirty percent more." ”

"That's right," Wang Dong exerted his amazing mental arithmetic instinct again, "a third more, that's more than 220 yuan, that is to say, for the same three stones of flour, our income can be more than 880 yuan." ”

Jiugong stroked his beard and smiled: "880 Wen, pay 780 Wen to Sanniang, we still have 100 Wen left, which can fully cope with other costs." ”

"That's right!" Wang Dong nodded excitedly.

But everyone didn't realize that at this moment, it was already the beginning of the lanterns, and it wasn't until the old lady came over with an oil lamp that everyone realized that it was already dark.

"I didn't expect it to be so late," Wang Dong turned his gaze to Jiugong and said, "Jiugong, I want to sort out today's content, so that I can show it to Sanniang." ”

"Well, among us, I'm afraid you are the only one who can explain these things clearly."

"Tomorrow's morning market ......"

Jiugong said with a smile: "I think, tomorrow we will still close business for a day, improve the new production process, and then start." ”

Wang Dong nodded: "It's just right, take advantage of this opportunity to write out the plan." ”

"Okay, that's it."

So, after reaching these consensuses, everyone split up and took action. Jiugong and the two servants fetched pen and ink and white cloth, and then made a large notice and hung it next to their morning market stall to explain that it would be closed for one day.

The lady of the Zhang family and another servant washed the utensils at home.

As for Wang Dong, he was thinking about how to write his plan to report to Meng Yao.

It's just that when Wang Dong was almost brewing, he found out tragically that he not only knew a little about the words of the Tang Dynasty, but even the "paper" used to write the plan was very different from modern times.

At this moment, Wang Dong was holding a wolf pen in his hand, looking at the huge piece of paper in front of him, a little dazed.

"Could it be...... A page of Datang, all so big? ”

In fact, Wang Dongcai is a shallow learner, the book of the Tang Dynasty is not bound into a book like in later generations, but a scroll-like thing, after it is written, the scroll is rolled up, and it becomes a book.

However, the appearance of the book is different, and the most terrible thing is that Wang Dong does not know the words of the Tang Dynasty at all, let alone write it with a brush.
