A Lifetime of Savings

Sometimes people who seem to lead what would be considered an ordinary life do extraordinary things. Such was the case with Oseola McCarty, who donated a large sum of money for a university scholarship fund in her name. Oseala lived her life taking in clothes that she would wash for people in a large kettle over a fire. Her donation became a legacy that inspired many others to donate. While Oseala's character could surely be considered impressive, wait until your students see the power of compounded interest! For this lesson, they will use geometric series to answer questions of Oseola's accumulated savings.
