Assume “Jane” saves $10,000 per year for 10 years starting at age 25. At age 35 she no longer is able to save but leaves her accumulated savings invested until age 65 when she retires. Assume “John” does not begin saving until age 35, but then saves $10,000 per year until age 65 when he also retires. Assume John and Jane invest their entire wealth in the same mutual fund.

At what assumed rate of return are John and Jane’s wealth at age 65 equal? Use “Goal Seek” in order to find this rate of return.
