Okay, so question one looks like it was cut off so all i can do is questions two and three for you right in here.
00:04
And so the first case, $1 ,000 deposit over five years earning 2 .6 % interest and it's compounded quarterly.
00:12
So one method i'm gonna do with this one is i'm gonna for five years, what i'm gonna do is i'm gonna find the difference between the four and the five years.
00:19
That will tell me how much interest is earned throughout that time.
00:22
So what i'm gonna do is i'm gonna set up with a is equal to p times 1 plus r over n raised to the nt power.
00:31
So we're going to do it for 5 years and 4 years and take the difference between those two.
00:35
So i'm going to do 1 ,000 times 1 plus 0 .026 divided by 4 raised to the 4 times 5 power minus 1 ,000 times 1 plus 0 .026 over 4 raised to the 4 times 4 power.
00:50
So when i do that, we've got 1 ,000 times 1 1 plus 0 .026 divided by 4, that's going to be raised to the 20th power like that, minus 1000 times 1 plus 0 .026 divided by 4 raised to the 16th power...
