prep 数学一道，求解，谢谢

According to the directions on a can of frozen orange juice concentrate, 1 can of concentrate is to be mixed with 3 cans of water to make orange juice.  How many 12-ounce cans of the concentrate are required to prepare 200 6-ounce servings of orange juice?

(A)  25

(B)  34

(C)  50

(D)  67

(E)  100

不是2006除以48吗？我怎么算都得不到25啊

prepare200个6ounce的果汁，你看错了吧...

6ounce里含concentrate和水的比例是1：3，所以1个6ounce果汁含1.5ounce浓缩液

200*1.5/12＝25
