Rewrite an Expression to Represent Discount | 7.EE.A.2 💚💙

In this short math video we will rewrite an expression to represent discount. We will be presented with a real world situation involving discount. We will read and interpret a given algebraic expression that represents the discount of an item 20% off. We will understand percent as a fraction and rewrite it as a decimal. We will review the invisible one in math and identify like terms. We will combine like terms to simplify an algebraic expression. We will identify the correct solution. An exemplar solution is modeled and explained.
