EXAMPLE 3: In June 2007, Manuel set up a TDA to save for retirement. He agreed to have $175 deducted from each of his monthly paychecks. The annuity s interest rate was allowed to change once each year. a. In 2007, the interest rate was 5.25%. Determine the account balance in June 2008. b. In 2008, the interest rate was 3.8%. Determine the account balance in June 2009. To do this, think of the June 2008 account balance as a lump sum that earns compound interest. c. In 2009, the interest rate was 2.2%. Determine the account balance in June 2010.
