一小瓶洗发水能装35毫升洗发水，而一大瓶能装500毫升洗发水。Jasmine想买最少数量的小瓶来完全装满一大瓶。她必须买多少瓶？

(A) 11 11

(B) 12 12

(D) 14 14

(E) 15 15

Answer

Correct choice: (E)

正确答案：（E）

Solution

Because $14 \cdot 35 = 490 < 500$ and $15 \cdot 35 = 525 \ge 500$, the minimum number of bottles that she needs to buy is 15.

因为$14 \cdot 35 = 490 < 500$且$15 \cdot 35 = 525 \ge 500$，她需要买的最少瓶数是15。
