(Calculating the future value of an annuity) Selma and Patty Bouvier, twins who work at the Springfield DMV, have decided to save for retirement, which is 35 years away. They will both receive an 8 percent annual return on their investment over the next 35 years. Selma invests $2,000 at the end of each year only for the first 10 years of the 35-year period—for a total of $20,000 saved. Patty doesn’t start saving for 10 years and then saves $2,000 at the end of each year for the remaining 25 years—for a total of $50,000 saved. How much will each of them have when they retire?
