In this question, we are going to solve a system of equations.
00:04
We must first write that system of equations to represent the given application, the given situation.
00:12
We have a child who has three different types of coins.
00:18
Pennies, i'll use a p, and nickels, n, and dimes.
00:24
And the child has 325 coins total.
00:27
There's our first equation.
00:30
We also know that there's a total value of $19 .50.
00:41
That's the same as $1 ,900.
00:45
I'm sorry, $19.
00:47
Yes, $19 .50.
00:49
That is the same as $1 ,950.
00:54
That'll make my second equation easier.
00:57
Each penny is worth one cent...
