※ 引述《koala0416 (koala)》之銘言：
: 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
: 答案給的是 D 為何要有兩倍的y呢?
出生-----------------被錄取-------退休
l----------------------l = x
l------------l = y
l-----------------------------------l = x+y
= 退休時的age，題目說退休時的age
再加上一個y要至少70
所以最低標準是(x+y)+y = x+2y = 70
