Jae-Min's dad & Jae-Min: AAAAAHHHHHH!!!
Narration: Huh? What's the matter?
Jae-Min's dad: Boohoo, what am I going to do, Dad? I have to go to school, boohoo.
Jae-Min's grandpa: I'm sorry, Jae-Min! Anyway, didn't I tell you never to touch that? But last night you just went on ahead and... Well, like father like son...
Jae-Min: Jae-min, would it be alright if I pack your bag like this? It's bigger than it looks. Well, it's perfect!
Jae-Min's dad: Dad!
Jae-Min: Hey, there's nothing we can do about this now. Crying isn't going to change us back. We might as well enjoy it! I'm going to school! Hooray!
Jae-Min's dad: Dad, are you sure you know what you're doing?
Jae-Min's grandpa: You just go have a seat over there and take it easy, leave this to me.
Jae-Min's dad: It's okay, Grandpa, I can do it.
Jae-Min's grandpa: Are you sure? Well, then I'll just pop out for a while. We're going to have to sort this out, aren't we?
Jae-Min's dad: Oh, what am I going to do? I was supposed to go to the bookstore with Kang-Ho and Se-Na today.
American 1(man): Hey, let's take a look in this shop.
American 2(lady): Alright!
Jae-Min's dad: Hey, they look like Americans. Gosh, I wish grandpa was here...
American 1(man): Hello!
American 2(lady): Is anyone here?
Jae-Min's dad: Hi, can I help you?
American 1(man): Hmm... How much is this?
Jae-Min's dad: It's \20,000.
Jae-Min's dad: Hey, that wasn't so bad... I'll just make the sale, and that'll be that!.
American 1(man): Here you go.
Jae-Min's dad: Hey, wait a minute.
Narration: What is Jae-Min going to do? He's never sold anything before. And now he's panicking because the Americans have paid him in dollars, not won.
Jae-Min: Hi, Jae-Min! Huff... Puff... Gosh, I ran all the way over here... Huff... Puff... Huh? It's me, dad!
Jae-Min: Jae-Min, what's the matter? Is something wrong?
Jae-Min's dad: Dad, he gave me American dollars. What am I supposed to do?
Jae-Min: What? Dollars? Just tell them we don't accept dollars here. They're a big hassle to try and calculate.
Jae-Min's dad: But dollars are money, too.
Jae-Min: Hmm... It's going to be a little tricky. Just tell the customers we don't accept dollars here.
Jae-Min's dad: I'm sorry, we don't accept dollars here.
American 1(man): \20,000?
American 2(lady): We don't have any more won.
American 2(lady): Can't you just take the dollars?
Jae-Min: We'll have to apply the currency exchange rate to the transaction.
American 1(man): The exchange rate? Aha!
Jae-Min's dad: The currency exchange rate?
Jae-Min: Yes. See, the currency exchange rate is always changing, so it's hard to know how much you need to pay us in dollars.
American 1(man): Aha! well, $1 was \1,000 when we came here, so for \20,000 we need to give you $20, isn't that right?
Jae-Min: No, if you want to pay us in dollars, you have to give us $21...
American 1(man): Why? Why would you charge us an extra dollar?
Jae-Min's dad: Just take the $20.
Jae-Min: The exchange rate changes all the time. So when we exchange money at the bank, it costs more if the exchange rate drops. If $1 drops to \900, $20 will only be equal to \18,000. So if you want to pay us in dollars you'll have to pay us a little more.
American 1(man): Well, that certainly makes sense, but...
Jae-Min: Or you could go to the bank across the street there and change some money.
American 1(man): Yes, I think I'll do that. Julie, wait here for a minute. I'll be right back.
American 2(lady): Okay.
Jae-Min's dad: Dad, what is the currency exchange rate? Can you explain it to me again? I didn't quite get it.
Jae-Min: Well, see how they wanted to pay us in dollars? But because we use won here, we need to take into consideration the currency exchange rate to calculate the transaction price. But you have to remember that the currency exchange rate is always changing.
Jae-Min's dad: So even if he'd given us $20, it could have been either more or less than \20,000?
Jae-Min: Hehe, that's it.
American 1(man): Ok, I'm back. Here's \20,000. The exchange rate's \900 to $1 now, even though it was \1,000 yesterday when we changed money at the airport.
Jae-Min: The currency exchange rate always changes, so if we accepted foreign currency we'd have to change our prices all the time. And then we could lose money if the rate dropped. That's why we have to ask for a little more when we accept payment in dollars.
Jae-Min's dad: Oh, so that's why. If you use the currency of the country you're in, you won't have any trouble buying things.
Jae-Min: Aha! When in Rome, do as the Romans do, right?
American 2(lady): Wow, this is really pretty!
American 1(man): Julie, I changed quite a bit of money at the bank, so if there's something you want go ahead and get it.
Jae-Min: You changed a lot of money? Well, then if there are lots of people changing dollars like you, the dollar's value ought to decrease.
Jae-Min's dad: Huh? What do you mean?
Jae-Min: The currency exchange rate is like the price of a commodity. If there is a large group of foreign visitors like you wanting to sell their dollars, the supply of dollars is higher, so then the dollar's value will decrease. And this means that the exchange rate will go down. But if many Korean people want to buy dollars so they can visit overseas, then the demand for dollars goes up, and so does the dollar's value. In this case, the exchange rate goes up.
American 1(man): Aha! So because I sold my dollars, the value of the dollar will fall, because more dollars are being sold?
Jae-Min: Hehe, that's correct.
Jae-Min's dad: Haha, isn't he a smart boy?
American 1(man): Yes, he certainly is. And we love the hat!
Jae-Min: Thank you! Bye!
Narration: Wow, Jae-Min's had Americans as his first customers. He didn't do too badly with the explanation of the currency exchange rate, either! But now, when will Jae-Min and his dad switch back with each other?
Jae-Min's grandpa: Ok, I found it! Finally! Gosh, that was so hard to find!
Jae-Min's dad: Really? Is that it? Can you hurry and change us back? I'm supposed to go to the bookstore with Kang-Ho today.
Jae-Min's grandpa: Well, there is just one little problem.
Jae-Min: What's that?
Jae-Min's grandpa: The transformation will take all night...
Jae-Min's dad: Grandpa! No!
Narration: Well, Jae-Min and his dad should be able to switch back after all. We can look forward to seeing them as themselves again in the next episode!
