Let's answer a question.
00:04
Given a percentage of decrease and an initial amount, explain how to find the final amount after a decrease.
00:13
Okay, so we're going to look for an explanation of how to find a total amount after a decrease.
00:17
A 30 % discount is to be applied to address with an initial price of 6599.
00:23
So let's start finding some of this out.
00:24
We have an initial price of 6599.
00:28
And i'm going to choose to write c.
00:30
For cost, 6599.
00:37
And it's helpful sometimes to put a little notation here.
00:40
So this is going to be our cost.
00:42
Why did i choose to use c? well, because we are going to be having a discount of 30%.
00:47
So sometimes i like to refer to that as the percent discount.
00:51
So i could have a percent here.
00:53
And we said it was going to be a 30 percent discount.
00:56
So it's going to be a 30 percent discount...
