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?

 

Thanks so much!

Amount  accumulated after 6 months  =

 

1000 ( 1 + .04/2) =  $1020

 

Amt  at the end  =

 

1020 ( 1 + .05/2)  =  $1045.50
