Question 1\ You are looking to start saving for retirement with the goal of living off the interest from your retirement savings when you are retirement, without using any of the principal from your savings. You currently do not have any other savings and will start making retirement savings contributions at the end of each month, starting 1 month from today. You come across this CNBC video which shows how much you would need to save monthly in order to be able to make withdrawals of $70,000 from your savings at the end of each year while you are retired, without using up any of the principal from your savings (i.e. you will only withdraw the annual interest earned). Use the assumptions outlined in the video.\ a. Compute exactly how much you would need in retirement savings in order to have $70,000 available at the end of each year in perpetuity during your retirement, assuming annual compounding while you are retired. Then, assuming monthly compounding while you are saving for retirement, show how the required monthly savings that are given in the video are computed if you are currently exactly:\ i. 25 years old ii. 30 years old iii. 40 years old\
