没有找到旧帖~~是不是太简单啦??

Q17:

To be eligible for retirement benefits at the Omega Corporation, the sum of an employee’s age, in years, and the number of years of employment must be at least 70. If x, where x < 70, is a certain employee’s age when hired and y is the minimum number of years of employment required for the employee to be eligible for retirement benefits, which of the following equations represents the relationship between x and y ?

A. xy = 70

B. x + y = 70

C. 2x + y = 70

D. x + 2y = 70

E. 2x + 2y = 70

为什么选D啊?

x+y是退休年龄

（x+y）+y就是那个和了啊

多谢版主回答~!!

题目问的是an employee's age 与number of years of employment的和至少70, X是员工被雇佣时的年龄, Y是员工年龄到70之间的差距,X+Y=70有什么不对的地方吗?

还是我对什么话的理解错误了?

哦~~~是不是我对"y is the minimum number of years of employment required for the employee to be eligible for retirement benefits"的理解有误?退休的年龄并不是70, 而是小于70的某个数, 那么确切的说70应该等于员工的退休年龄与工龄的和.Y是员工年龄与退休年龄之间的差距, 并且是使员工有资格拿到退休金的最低值.所以答案是X+2y=70

谢谢版主~~!!

我刚才明明把帖子发上来了啊, 怎么一下子就看不到了呢? 我明白我错在什么地方了, X是员工被雇佣时的年龄, Y是员工被雇佣的年龄与退休年龄之间的差距,且这个值使员工的退休年龄与工龄之和为70.

X+Y=退休年龄

Y=工龄,

70=退休年龄+工龄

我错在以为退休年龄可以为70,Y是员工年龄与70之间的差距.阅读可真是重要啊~~!!!
