Writing Equations from Word Problems

This video tutorial teaches how to translate word problems into algebraic equations by defining variables and constructing equations. It covers two examples: Mia's revenue from selling pumpkins and apple baskets, and Michelle's cell phone costs based on minutes and texts. The video emphasizes understanding the components of each problem to form a correct equation.

What is the first step in translating a word problem into an algebraic equation?

• Check the solution

• Solve the equation

• Define the variables

• Graph the equation

In the first example, what does the variable X represent?

How is the total monthly cell phone cost calculated in Michelle's problem?

• Cost per minute times number of minutes

• Cost per text message times number of text messages

• Sum of cost of minutes and cost of text messages

• Total number of minutes and text messages

What is the total monthly cost for Michelle's cell phone?

• $180.50

• $200.00

• $196.80

• $150.00
