These are the two equations we came up with.

With substituting, as I said, the i and the A with the Ps.

So the first equation will give you P,

which if instead of doing, or what we went through one by one.

Calculating P 1, P 2, P 3, all the way to P 36, we can use the first equation.

We can say okay, if A I give you is $968 for

an substitute A here, 968.

The i, we can't have it as the point O, O 833.

The N is 36 months and P then has to give you $30,000.

And this is the opposite.

If I can tell you, okay, this is the $30,000 and

you have an i equal to 0.833% per month.

And you have an n or number of interest period which is 36 months,

what will be the equivalent A for the next 36 months?

What you will do is to apply 50,000 for the P here,

the i the 0.833, the n is 36 all the way,

and you have to get with the number $968.

So these are the two equations that we will be using

along moving forward in case we have a connections between, and

we want to understand or calculate that uniform series with a present worth.

Now, things I want you to remember about the uniform cities values

are the following.

One, all payments must be equal.

If you want to use the previous two equations that I just highlighted,

that you have to have in the cash flow diagram.

Let's say you have all the way here to n.
