The Day of the Draw at Hogwarts

Tom was also on the side, listening in on the question.

This question is quite complicated. The root of the complexity comes from the morbid currency conversion system in the magic world. 1 gold Galleon can be exchanged for 17 silver xikes, and 1 silver xican can be exchanged for 29 copper nut.

Tom really doesn't understand. Why did you choose two prime numbers as conversion units? Isn't decimal and decimal not fragrant? Even if the wizarding world wants to differentiate itself, why not choose the most magical number 7?

Incomprehensible.

However, it is still possible to make a rough judgment. The Complete Works of Lockhart is worth 35 Galleons, and the 10% discount is 31.5 Galleons. Whether or not to give change depends on whether the remaining book fee is enough for 2.5 Galleons.

3 Galleons and 9 Sikes, according to my feeling, even if I get a 20% discount, it is still more than 2.5 Galleons, so that person needs to make up for it.

But then Tom was a little dumbfounded: I'm afraid I need to do a good calculation on how much to make up.

Hermione: …

She looked like she was overloaded with calculations. The whole person stopped for a while. In the end, her eyes rolled and she was short of breath, but she couldn't come up with a result. In the end, she took out a pen and paper and calculated it by hand. Come to the conclusion: "367.5 nut, which is 12 ticks and 19 nut?"

Lawrence took out what looked like a typewriter, and began to crack it. After a while, he nodded, "It is indeed the money to erase the fraction."

Seeing that Tom and Hermione were both looking at the machine, he smiled a little embarrassedly, "This is a calculator, to be honest, I deliberately made things difficult for you with the question just now, we don't usually have such a thing in our store. fancy discounts…”

Then he showed Tom and Hermione how to use the calculator. The calculator is covered with metal gears and levers, giving it an unintelligible look.

The method of use is not complicated. There are three glass rollers on the left side of the calculator, which correspond to the gold Galleons, Silver Sikes, and Copper Nat paid by customers respectively. There are five scroll wheels on the right, where the price of the book is entered. The first three are currency units, the second to last is the discount amount, and the last one is confirmation. After pressing confirm, you can enter the price of the next book. If you press it twice, it means that all book prices have been lost, and the machine will start to calculate. Below the machine, there are also three rollers, where the change is displayed.

Tom and Hermione looked at the calculator with complicated expressions: there were too many flaws and they didn't know how to complain for a while.

"So if you get a wrong number, you have to lose all of them, right?" Hermione found the crux of the problem.

Lawrence: …

"You actually got the correct answer by just calculating with a pen?"

Hermione: "It's nothing, I'm just more sensitive to numbers."

Tom & Lawrence: …

Lawrence coughed twice, "Actually, because it's too troublesome to calculate, Lihen Bookstore basically won't offer any discounts. I'll test you a few more questions."

So Mr. Lawrence came up with a few more questions. This time, since there was no discount involved, Hermione's calculation was much faster, even faster than Lawrence's calculator.

"Merlin is here!" Mr. Lawrence scratched his thinning hair. He thought that Hermione was a monster. It was incredible.

"She is the first in our grade." Tom reported Hermione's identity.

Lawrence's eyes drifted between the two for a while, and without saying anything, he took Hermione to sign the contract.

After Hermione signed the contract, Lawrence gave each of them a vest with the trademark of Lishen Bookstore, and Tom and Hermione were part of Lishen Bookstore.

Hermione was in charge of the cashier at the front desk, and Tom was in charge of restocking the bookshelves.

For Hermione, the work in the bookstore is very leisurely, and there are not many customers on weekdays. Many people just come in and walk around and go out, which results in not much work for Hermione. Her working hours are also normal, just in time for the bookstore's business hours: 9:00 am to 5:00 pm. Tom came an hour earlier than her, tidying up the shelves. Hermione worked five days a week for ten Galleons a week.

Tom is a little busy. He needs to take out the new books from the warehouse and put them on the bookshelf. At the same time, he needs to put the few books on the shelf in the small books, and then go back to the warehouse to make up. However, since there were not many books sold, and the best-selling books were only those few, Tom became proficient with only a few trips.

Soon, Tom finished his work and started to fish with confidence. He sat on the small stool next to the cashier, with his hands on the table, tilted his head and looked at Hermione.

Hermione was long out of work - the last customer checked out a quarter of an hour ago. At this time, she was reading a best-selling book called "Break With a Female Ghost" with gusto. She felt someone watching her, and as soon as she put the book down, she saw Tom laying his head on the cashier, staring straight at her.

Hermione's face flushed, and she patted the book directly: "What are you looking at? Go back to your work!"

"But my life is over."

"Then find a book to read!"

"Is this book good-looking? This author's book is selling very well recently. UU Reading www.uukanshu.com"

When talking about books, Hermione opened her chatterbox and began to talk about her feelings after reading it. Tom listened quietly beside him, just like a stand-up comedy. But after listening for a while, he also came up with the idea of ​​looking for a Lockhart book to read.

So he took a look at Lockhart's novel. It didn't matter at first glance, Tom was also attracted by the story in it. Lockhart's stories are "adapted from real events", and with good writing, naturally many people buy it.

This is the end of the first day of work. At five o'clock in the afternoon, Tom and Hermione left the Flourish Bookstore after cleaning up. Hermione took Dad's car home through the Leaky Cauldron, and Tom went back to Ollivander's wand shop.

Back at the wand shop, Mr. Ollivander also finished his work. He stood up with a smile and handed Tom a thick book and a half-size box.

"You should read this first in the past two days, combined with the contents in the box."

Only then did Tom know that the big book was an illustrated book of wand materials, and the box contained samples of various materials. Mr. Ollivander left the book after handing it to Tom. But Tom did not go back to the dormitory immediately, although Mr. Ollivander did not say, he still cleaned the shop a little, swept the floor, wiped the counter: this is the duty of the apprentice.

After that, he lived in the house provided by Mr. Ollivander. The house is just behind the wand shop. It is not large, and the interior decoration is very simple: only a bed, a chair, a table and an oil lamp. There is also a small cubicle next to the house, and the bathroom and toilet are two-in-one.

This is where Tom will live for the next two months. The room is simple, but clean, and the furniture feels just right.
