Question

一袋 $350$ 克的咖啡豆说明上写着：正确冲泡一大杯手冲咖啡需要 $20$ 克咖啡豆。用这袋咖啡豆最多可以正确冲泡多少大杯咖啡？

The instructions on a $350$ -gram bag of coffee beans say that proper brewing of a large mug of pour-over coffee requires $20$ grams of coffee beans. What is the greatest number of properly brewed large mugs of coffee that can be made from the coffee beans in that bag?

$16$

$17$

$18$

$19$

$20$

答案：B

知识点：取整函数

难度评级：890

解答：

每杯需要 $20$ 克，而 $\dfrac{350}{20} = 17.5$ 。由于只能冲泡完整的一杯，最多可冲 $17$ 杯。

所以正确答案是 B。

Each mug uses $20$ grams, and $\dfrac{350}{20} = 17.5.$ Only complete mugs can be brewed, so the greatest number is $17.$

Thus, the correct answer is B.
