Your friend is celebrating her 35th birthday today and wants to start saving for her anticipated retirement at age 65 (she will retire on her 65th birthdav). She would like to be able to withdraw $80,000 from her savings account on each birthday for 20 years following her retirement (the first withdrawal will be on her 66th birthday). Your friend intends to invest her money in the local savings bank which offers 4% p.a. compound semi-annually. She wants to make equal annual deposits on each birthday in a new savings account she will establish for her retirement fund. If she starts making these deposits TODAY and continues to make deposits until she is 65 (the last deposit will be on her 65th birthday), what amount must she deposit annually to be able to make the desired withdrawals upon retirement? Any intermediate steps should be rounded to 4 or more decimal places. Round your final answer in dollars to 2 decimal places and exclude the dollar sign ($). For e.g., $10,784.6518 should be input as 10784.65.
