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?

一袋350克的咖啡豆的说明上写着，冲泡一大杯手冲咖啡需要20克咖啡豆。从这袋咖啡豆中能冲泡出的最多大杯手冲咖啡的数量是多少？

(A) 16 16

(B) 17 17

(D) 19 19

(E) 20 20

Answer

Correct choice: (B)

正确答案：（B）

Solution

$\frac{350}{20}$ is $17.5$. We round down to find the maximum he can make (he cannot brew half of a cup), so the answer is $\boxed{\text{(B) }17}$.

\frac{350}{20}=17.5。我们向下取整以找到最大能冲泡的数量（不能冲泡半杯），所以答案是\boxed{\text{(B) }17}。
