    Investment Interest Accumulation

    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 $5\%$ that also compounds semi-annually. After six months in the second CD, how much does Dr. Zaius have, in dollars?
