How Much
adverb, noun
This has the same meaning as the kanji, specifically the how much meaning. To remember this, just think about how Ra, the Egyptian God, is always asking "How much will it cost to build this pyramid?" Ugh, too much, let's hire some slaves.
Since this word consists of a kanji with hiragana attached, you can bet that it will use the kun'yomi reading. You learned this reading already so you should be able to read it!
これはお幾らですか？
How much is this?
幾ら探しても、見つからなかった。
No matter how much I searched, I couldn't find it.
幾らかのトラブルはありましたが、何とか無事に終わりました。
There were some troubles, but it ended safely somehow.
送料が幾らになるのか教えていただけませんでしょうか。
Could you tell me how much the shipping will be, please?
