Homework Help: Math

Posted by Lydia on Saturday, October 15, 2011 at 9:17am.

Lee Holmes deposited $16,600 in a new savings account at 9% interest compounded semiannually. At the beginning of year 4, Lee deposits an additional $41,600 at 9% interest compounded semiannually.

At the end of year 6, what is the balance in Lee’s account?
I have tried and I got $44691.78 but that is incorrect. I solved each part separately then added the what he deposited. PLEASE HELP ME!!

It's not quite clear from the language, but it appears that after 3 years, an additional deposit was made, and then the current balance is left to draw 9% interest for two more years. If that's the case, then

to start: 16600
at the end of year 3, he has 16600*1.045^6 = 21617.52

Add 41600 = 63217.52

After two more years, 63217.52*1.045^4 = 75388.07

Oops. That just takes us 5 years.

63217.52*1.045^6 = 82325.66

Make a time graph to see how the periods work

amount = 16600(1.045)^12 + 41600(1.045)^6
= 82 325.65
