Your first deposit will equal $500, each of your subsequent quarterly deposits will grow by 1% each, and your final quarterly deposit will occur two years and eight months from today. From this account you plan to make semiannual withdrawals beginning three years and one month from today. Subsequent semiannual withdrawals will shrink by 2% each and your final withdrawal will occur five years and seven month from today. DO IN EXCEL WITH FORMULAS VISIBLE PLEASE
