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 50, 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.
Choose the correct choice from the following answers:
A) K+35 B) 2K+35 C) (70+K)/2 D) (50+K)/2 E) 2(70-K)
Say Sue was hired when she was already 50 years old (k=50), then she could retire right away, at the age of 50. Now, plug k=50 in the answer choices and see which yields 50. Only C fits.   Answer: (50+K)/2.
