Question 2 (15 points) Antonia is celebrating her 30th birthday today and wants to start saving for her anticipated retirement at age 60. She wants to be able to withdraw USD 90,000 from her retirement fund account on each birthday for 15 years following her retirement; the first withdrawal will be on her 61st birthday. Antonia intends to deposit her money in Citibank, which offers 8% interest compounded annually. She wants to make equal annual payments on each birthday into the account established at Citibank for her retirement fund. (a) If she starts making her first deposit on her 31st birthday and continues to make deposits until she is 60 (the last deposit will be on her 60th birthday), what amount must she deposit annually to be able to make the desired withdrawals at retirement? (10 points) (b) Suppose Antonia has just inherited a large sum of money. Rather than making equal annual payments, she has decided to make one lump-sum payment on her 30th birthday to cover her retirement needs. What amount does she have to deposit? (5 points)
