I found an unusual vending machine at a subway station. The machine sells soft drinks, and it has a sign that helps foreign travelers pay for the drinks. If you have ever traveled in a foreign country, you know that it can be difficult to pay for something. You don’t know the money of the country, so you have to look at each coin and figure out how much it is worth. The sign on this machine is very helpful. It shows the coins that you need to pay for a drink. If the drink costs 130 yen, it shows one 100-yen coin and three 10-yen coins. If the drink costs 160 yen, it shows one 100-yen coin, one 50-yen coin, and one 10-yen coin. 　(125 words)
