The formula above gifts, the monthly payment needed to pay off a loan p dollars that are percent annual interest over n months. Which of the following is p in terms of M r? and way too many variables in this question? Wait a minute, okay. So really what they want is for you to just isolate p, so we're going to have a p is equal to something with m, r and n. And where are these guys? Well, that's our, that's an N, that's an N, and here is our P. Okay?

So if you want to isolate this, right, you remember, we want to get everything on one side, and we're just going to leave p on one side all by its lonely self. Okay, so how do we do that? Well, we want to get this and this, and that out of here. So I'm going to call this guy right here, x, this one, y, and this one, z, just to make things a little clearer. So what is this actually, it's just going to be m is equal to f. Y over z times P. So what is p? Well P is just going to be equal to z, M over x, y.

Okay, so what are its choices is going to look something like this. And what is z? z is this mess down here, this whole thing. So which one of answers has that on the top? Okay, so a does not just have that on top, it has m, and it has some other stuff so, absolutely not. What about B?

Oo B looks like a good candidate. Well, let's hold that for a second. See, oh man, C and D are no goes okay? Those guys are just not even close. So there you go. Our answer is our good friend v.
