テニスの試合で甲府に来ていますが、なんか変？おもしろいって思ってしますので、取り上げてみました。
ドラッグストアーで栄養ドリンクを見ていて？
最初に10本398円をみてやすーと思ったんですが。
一本売りは88円。
10本だと880円だけど、50％以下の398円
いったい原価はいくらなんだろう？
I am here in Kofu for a tennis match. I thought it was interesting when I went to the drugstore, so I took it up.
I was looking at nutritional drinks at the drugstore.
When I first saw 398 yen for 10 bottles, I thought it was so cheap.
The price for a single bottle was 88 yen.
Ten bottles should cost 880 yen, but the price was 398 yen, less than 50% of the original price.
How much is the cost?
