The restaurant owner bought two hundred pounds of potatoes which contain 99% water content. The potatoes are left in the sun for 4 hours. Now the total water content of the potatoes is slightly reduced to 96%. What is the total weight of the potatoes now?
选项
A、194.06 pounds.
B、192.08 pounds.
C、150 pounds.
D、50 pounds.
答案
D
解析
假设蒸发掉的水的重量为x,根据题意,可以得出如下方程式:(200×99%-x)/(200-x)=96%。得出x=150,现在土豆的总重量为200-150=50(磅)。
