Today is Dec. 31, 2020. Jane is planning to retire in 40 years from today, similar to John introduced in Question 2 . Jane also believes she needs to save money to support her living for 20 years, i.e., 2061 through 2080, after her retirement. However, Jane estimates that she will need $50,000 for 2061 and that this will then grow at a rate of 5% each year from 2062 to 2081. Assume that the interest rate is 10% and will be constant over time. Determine how much she needs to save by the end of 2060.
