Keon has just graduated from college with a business management degree. Through part-time work and trading stocks, he has amassed significant savings which he is considering investing in a small business venture. Historically, Keon has earned a 9% annual return on his investments, but he realizes that he can't expect| the same results with full-time employment or entrepreneurship. He hopes to earn 5.50% a year going forward, should he decide to leave $70,000 invested in a relatively safe investment portfolio. As a result of his trading success, Keon has been offered a job as a junior analyst at a major investment management firm. The job would pay $60,000 to start, with a promotion expected in a year. At that point, the salary would increase to $72,000, followed by steady $2,000 increases annually
