Things are asking us here.
00:01
We want to using the appropriate compound interest formula.
00:05
So i'm going to use the general compound interest formula, which is written on the screen.
00:09
In the first one, we have $16 ,000.
00:13
So that's going to be our principal.
00:15
It's an invested at a rate for five years.
00:21
And it's invested at a rate of 3%.
00:24
Now it doesn't say that it's compounded in any other way, but annually.
00:29
So i'm going to go ahead and just use annual.
00:31
As our rate.
00:32
So that means that our value of n is going to equal to 1.
00:36
So we're going to have a equals 16 ,000, 1 plus our interest rate we always change to a decimal.
00:44
0 .03 over 1 to the 1 times 5.
00:48
So let's just go to our calculator.
00:51
1 plus 0 .03 divided by 1 and we're going to raise that to the 5th power.
00:57
Our balance would be $18 ,548.
01:01
And $39...
