6. Comparing retirement plans. Alexa Rollins has just graduated from college and is consid- ering job offers from two companies. Although the salary and insurance benefits are similar, the retirement programs are not. One firm offers a 401(k) plan that matches employee contribu- tions with 25 cents for every dollar contributed by the employee, up to a $10,000 limit. The other has a contributory plan that allows em- ployees to contribute up to 10 percent of their annual salary through payroll deduction and matches it dollar for dollar; this plan vests fully after five years. Because Alexa is unfamiliar with these plans, she turns to you for help. Explain the features of each plan so that Alexa can make an informed decision
