Dr. Zaius invests $10,000 in a CD with an annual interest rate of 4% that compounds semi-annually (twice a year). After six months, he rolls over the CD into another CD with an annual interest rate of 6% that also compounds semi-annually. After six months in the second CD, how much does Dr. Zaius have, in dollars?

10,000 x 1.02 ==10,200 - principal + interest for the first 6 months.

10,200 x 1.03 ==**$10,506 - principal + interest after the second 6-month period.**
