For an employee to qualify for early retirement at a certain company, the sum of the employee’s age and years of service must be at least 72, If Sue was K years old when she was hired by the company, what is the minimum age at which she could possibly qualify for early retirement.	Answers:
A) K+36  B) 2K+36  C) (72+K)/2  D) (72-K)/2  E) 2(72-K)
Let y be the years of service at the company.   After y years of service, Sue's age will be K + y.   Sue can retire when (K+y) + y = 72   y = (72 - K)/2   Then Sue's age will be K + y = K + (72 - K)/2 = (72+K) / 2   The answer is (72+K)/2.
