All right, we got stanley.
00:03
He's got a credit card.
00:05
He goes to the grocery store and he buys some grocery.
00:08
In fact, he buys $100 worth of grocery.
00:12
All right.
00:13
Now, he paid with a credit card and this balance on the credit card is going to grow.
00:17
So we have 100 % of that.
00:19
It's going to grow by 4 .5%.
00:23
And we're going to write that as its actual number.
00:27
It's decimal.
00:28
So 0 .045.
00:31
And that's going to grow 4 .5 % each month.
00:35
All right, so i'm going to use just a letter m to represent that.
00:38
Let me take this 4 .5 % away.
00:42
All right, so this is a model now that could function, or that models the situation, function that models in this situation.
00:51
All right, i could simplify it...
