So this problem gives us, it's a word problem and asks us to write a system equation and then solve it.
00:05
So it tells us that adult tickets, which i'm going to call x, cost $22.
00:11
It tells us that children tickets, which i'm going to cost, i'm going to call y, cost $15.
00:19
It tells us that there are 11 people and the total is $228.
00:26
So now we have to write and solve a system of equations.
00:29
I'm actually over here.
00:32
So we know there are 11 people total, which means that x means that x plus y equals 11.
00:40
Now we know that the total is $228, which means that the number of adults there are x times the price for an adult plus the number of children, y times the price of a child's ticket, is going to equal $228.
00:58
So i'm just going to rewrite this.
01:01
I'm going to do x, 15, y.
01:06
All right.
01:06
So now we have a system equation that we can solve.
01:09
I'm going to get rid of this and this to give us some more space...
