Through automatic transfer from her bank Cherubini account to her savings account, Lily has made deposits of $145 at the beginning of each month. The savings account earns interest at 2.12% compounded semi-annually. After 12 years, how much has she accumulated in her savings account? This is an annuity due because she is making payments at the beginning of each month. The question is asking what the future amount is so it is a future amount we are looking for. The formula I chose is Sn(due) = R(1+I)((1+I)n -1)/i. The answer is $23,780.54. $145 x 12 x 12 = $20,880. n = 12 years x 2 compounded periods = 24. I am having difficulty getting the answer. What am I doing wrong
