All right, the problem we're going to look at today is a system of equations problem.
00:06
And the situation is that we have paula, who's planning a school dance.
00:13
And she wants to make this dance as economic as possible for students to attend.
00:20
So she's trying to decide which band she's going to hire.
00:24
So she has band a.
00:26
We're going to call it band a.
00:27
And they want to charge her $600 to come to the dance.
00:36
Then she has another band that she's considering.
00:40
We're going to call it band b, and they're going to charge her $350 plus they're going to charge her $1 .25.
00:51
Plus they're going to charge her $1 .25 for every student that comes to the dance.
00:58
So i'm setting up a variable x that's going to equal the number of students who come to the dance.
01:09
So we've got two equations that represent each one of these situations...
