Lesson Excerpt:

We all know that prices change over time.  The price of food has increased, the price of a movie ticket has increased, and the price of gasoline has increased.  It goes on and on, we could make a list of all of the prices that have increased in the past few years.
When prices increase, we can figure out by what percentage they have actually increased.  We call this the percent of an increase.

How can we figure out the percent of an increase?
To figure out the percent of an increase, we are going to need to compare prices and to compare the change or difference between those prices.

Let’s look at an example to better understand this.

The price of a stamp many years ago was 5 cents.  Today, the stamp has increased to be 43 cents.  That is a huge increase.  What is the percent of the increase?

To solve this problem, we are going to need to work through a couple of steps.
