Converting Real-World Situations into Equations

What is a variable in the context of equations?

• A fixed number

• A letter or symbol representing an unknown number

• A mathematical operation

• A type of equation

What is the total cost of the trip to the state fair?

• $63

• $11

• $52

• $22

How many passes are included in the trip cost?

• One

• Two

• Four

• Three

What is the first step in writing an equation from a real-world situation?

• Solve the equation

• Identify the variables and the constant

• Graph the equation

• Check the solution

If x represents the cost of each pass, what equation represents the total cost of the trip?

• x + 11 = 52

• 2x + 11 = 52

• 2x = 52

• x = 52
