Problem
A woman makes an investment every 3 months at a nominal annual interest rate of 28%, compounded quarterly. Her first investment was $100, followed by investments increasing $20 each 3 months. Thus, the second investment was $120, the third investment $140, and so on. If she continues to make this series of investments for a total of 20 years, what will be the value of the investments at the end of that time?
