Question

一个小洗发水瓶可装 $35$ 毫升洗发水，而一个大瓶可装 $500$ 毫升洗发水。Jasmine 想购买最少数量的小瓶，足以完全装满一个大瓶。她必须买多少瓶？

A small bottle of shampoo can hold $35$ milliliters of shampoo, whereas a large bottle can hold $500$ milliliters of shampoo. Jasmine wants to buy the minimum number of small bottles necessary to completely fill a large bottle. How many bottles must she buy?

$11$

$12$

$13$

$14$

$15$

答案：E

知识点：取整函数估算

难度评级：880

小提示：

计算 $500$ 除以 $35$

Divide $500$ by $35$

大提示：

因为 $14$ 瓶不够 $500$ ，要把商向上取整

Since $14$ bottles fall short of $500,$ round the quotient up

解答：

十四瓶可装 $14 \cdot 35 = 490$ 毫升，这还不够。十五瓶可装 $15 \cdot 35 = 525$ 毫升，已经足够。

所以 Jasmine 需要 $15$ 瓶。

因此，正确答案是 E。

Fourteen bottles hold $14 \cdot 35 = 490$ milliliters, which is not enough. Fifteen bottles hold $15 \cdot 35 = 525$ milliliters, which suffices.

So Jasmine needs $15$ bottles.

Thus, the correct answer is E.
