Thank you for visiting。

I don't dislike math、munejyuka。

My policy was to solve the problem elegantly...

I've been interested in it for a while when I shop in the store.、The price tag is displayed to the decimal pointIt may happen。

Will this decimal point be rounded up?、Will it be truncated?

I was curious so I decided to buy it at the supermarket and check it out.。

Let's take a look!

I bought Sapporo Black Label 500ml

I bought this time、Sapporo Beer's、Sapporo Black Label 500ml。

The price tag is、The product cost is 248 yen、Next to it, tax included、

272.8 yen

It was displayed as。

The problem is 0.8 yen below this decimal point。

If you round it up, it's 273 yen.、If you cut it off, it will cost 272 yen.。

Check it on the receipt、

It was 10% tax and 24 yen.、The total is

272 yen

was。

I felt a little relieved。

A side note though、As the number increases...

Still、This time there was only one bottle so it cost 272 yen、The more the number, the more results。

For example、What happens when you buy 10 bottles in bulk?、

The product price is、

248 yen x 10 bottles → 2480 yen

Next、If you impose 10% consumption tax、

２４８０×１.１→2,728 yen

Will be。

If I bought one bottle it would cost 272 yen.、If you buy one 10 times

2,720 yen

Will be。

So、If you buy 10 bottles in bulk, you'll have to pay 8 yen extra.。

…

8 yen...

Here、I wrote about it above earlier、

It says 0.8 yen below the decimal point

It has become a presence。

If the display is 272 yen、Those who buy 10 bottles will pay 2,720 yen.。

It's a little expensive to hear that it costs 1880 yen for 37 kg! You might think that、If it is displayed as 272.8 yen including tax、Those who buy 10 bottles will pay 2,728 yen.。

As for the store side、I think this 8 yen is big。

If dust accumulates, it won't turn into a mountain、You receive a few yen more payments as many customers as you can、If that continues every day...

This is、It's the magic of consumption tax。

Round up to the decimal point、It has nothing to do with truncation...

Let's leave this to think about it。

I use it normally when talking in conversation

For the amount below the decimal point of the consumption tax、I looked into rounding up and truncating。

The supermarket I bought this time was cut off.。

Do not display decimal places、It is thought to be based on the shop's judgment.。

actually、Some stores only display prices including tax, so please be aware that。

However、That's、There may be some shops that have already set prices a little higher...

I don't think it's possible to say which one is。

The store's convenience、The buyer cannot decide、I have no choice but to deal with that。

Smart、I want to shop!

Please read to the end、thank you very much!
