Okay, so if $6 ,000 is invest into a baking account with a interest rate at 10 % per year, so we're going to use a equals 6 ,0001 plus your rate of 0 .0 .10 % over n, which is how long it's going to compound annually? so the first one is nine years compounded annually.
00:39
So i'm going to do it as 6 ,0001 plus 0 over 1, and then 1 times 9.
00:51
So we really didn't need the fraction or the 1 on this one because they're both understood.
00:56
But just because it's part of our, it helps to use the same formula to keep from getting confused, i decided to go ahead and include it.
01:13
Okay? so this is going to be $14 ,147.
01:22
And 69 cents.
01:26
The next one is compounded quarterly.
01:29
Quarterly means four times per year.
01:31
So that means our n is going to equal four.
01:34
After nine years, so 6 ,000, parentheses, 1 plus 0 .10 over 4.
01:43
And then four times nine.
01:59
And then put that in the calculator, and that gives you $14 ,595 .25...
