Teaching Materials

Lesson Excerpt:

To calculate a sales price, you first have to calculate the amount of a discount.

**Do you remember how to calculate a discount?**

If you know the original price of an object and the % of the discount, then you can calculate the discount off of the original price.

Let’s look at an example.

Example:

John is buying a new guitar. The original price is $65.00. It has been marked 15% off. What is the amount of the discount?

To work on this problem, we can write this another way.

**What is 15% of 65?**

Next, we need to write an equation.

“What is” becomes x =

15% becomes a decimal .15

“of” means to multiply

**Now we can write an equation**.
