日本には五百円玉というものがあります。
Japan has 500-yen coins.
「どうやって五百頭もの馬を車に乗せるっていうの？」と女が聞いた。「そうだよね。代わりにバンを持ってきた方が良かったかな。」と男は答えた。
"How are we going to get five hundred horses into one car?" asked the woman. "You’re right! Do you think I should have brought the van instead?" the man replied.
When you have five hundreds you also have five hundred.
This word uses the on'yomi readings for both kanji, so you should be able to read it already!
