Model Algebraic Equations

Violet bought a notebook for $12.50 and 9 pens. Her total was $43.73. Which equation models the situation if the price per pen is x?

• 12.5x +9 = 43.73

• 73.43 = 12.5x + 9

• 12.5 - 9x = 43.73

• 43.73 = 12.5 + 9x

Sidney bought pizza and soda for a party. If she spent $12.57 on the sodas and $10.95 for each pizza. Her total is $89.22. Which equation models the situation if she bought x pizzas?

• 10.95x + 12.57 = 89.22

• 12.57x + 10.95 = 89.22

• 89.22x -10.95 = 12.57

• 12.57 + 10.95 = 89.22
