1. Evie and Ellie are twins. They decide to save for retirement, which is 48 years away. They will both receive a 4% annual return on their investment over the next 48 years. Evie saves $5,000 at the end of each year only for the first 16 years. Ellie does not save anything for 16 years and then saves $5,000 per year at the end of each year for the remaining 32 years. (Evies first retirement contribution is at t = 1 and her last retirement contribution is at t = 16. Ellies first retirement contribution is at t = 17 and her last retirement contribution is at t = 48.) How much will each of them have when they retire in 48 years?
