### 1. How to Find Simple Interest Rate: Definition, Formula & Examples

When we borrow a certain sum of money over a period of time, we agree that we will pay it back, along with a fee, known as the interest owed. Similarly, when we invest a sum of money in a savings account, the account earns us interest. This lesson will show you how to calculate a certain type of interest called simple interest.

### 2. Compounding Interest Formulas: Calculations & Examples

Compound interest is a great way to have your money work for you. In this lesson, find out the formula for calculating compound interest and practice using the formula with several examples.

### 3. Markup & Markdown: Calculation & Examples

After watching this video lesson, you will become familiar with how stores price their products to make a profit. Learn about how they increase their prices, markup, and how they decrease their prices, markdown.

### 4. Commission & Profit: Definitions, Equations & Examples

When a business sells a product, it needs to know if it is making money, and employees need to know how their pay is calculated. In this lesson, you will learn about calculating profit and commission.

### 5. Parabolas in Standard, Intercept, and Vertex Form

By rearranging a quadratic equation, you can end up with an infinite number of ways to express the same thing. Learn about the three main forms of a quadratic and the pros and cons of each.
