2. Carla is interested in saving for retirement. Today, on her 40th birthday, she has $100,000 in her investment account. She plans to make additional contributions on each of her subsequent birthdays. Specifically, she plans to: Contribute $10,000 per year each year during her 40s. (This will entail 9 contributions--the first will occur on her 41st birthday and the 9th on her 49th birthday.) Contribute $20,000 per year each year during her 50s. (This will entail 10 contributions--the first will occur on her 50th birthday and the 10th on her 59th birthday.) Contribute $25,000 per year thereafter until age 65. (This will entail 6 contributions--the first will occur on her 60th birthday and the 6th on her 65th birthday.) Assume that her investment account has an expected return of 11 percent per year. If she sticks to her plan, how much will Carla have in her account on her 65th birthday after her final contribution?
