(a) Patty Stacey deposits $1200 at the end of each of 5 years in an IRA. If she leaves the money that has accumulated in the IRA account for 25 additional years, how much is in her account at the end of the 30-year period? Assume an interest rate of 11%, compounded annually. (Round your answer to the nearest cent.) $ (b) Suppose that Patty's husband delays starting an IRA for the first 10 years he works but then makes $1200 deposits at the end of each of the next 15 years. If the interest rate is 11%, compounded annually, and if he leaves the money in his account for 5 additional years, how much will be in his account at the end of the 30-year period? (Round your answer to the nearest cent.) $ (c) Does Patty or her husband have more IRA money?
Use a series to model the situation in each of the following problems. Cleo deposited $\$ 1000$ at the beginning of each year for 5 years into an account paying $10 \%$ interest compounded annually. Write a series using summation notation to describe how much she has in the account at the end of the fifth year. Note that the first $\$ 1000$ will receive interest for 5 years, the second $\$ 1000$ will receive interest for 4 years, and so on.
