So if we have a sinking fund, the way we find the periodic payment is the pmt.
00:08
Let's say that's going to be equal to the future value to project, or that is projected times i over 1 plus i to the n minus 1.
00:24
So let's identify what everything is.
00:25
So we already said the pmt is your periodic payment.
00:36
The future value is fv.
00:43
Let's see, i is going to be the interest rate per period.
01:00
So whatever the interest rate is, and r will be the interest rate, and that should be in a decimal.
01:11
So whatever the interest rate is, you'll divide that by the period, and that will give you your i.
01:17
And then n is going to be the total number of payments.
01:24
So let's list what we actually have.
01:31
We are given that we have an interest rate of 0 .06, or 6%, and it's compounded monthly.
01:50
We also have that our future value is projected to be $82 ,000.
01:57
The total time, which is not really a variable, but the time is going to be nine years, which is going to be equal to 108 months...
