Mallory bought pizza and soda for a party. If she spent $12.57 on the sodas and $10.95 for each pizza, how many pizzas (x) did she buy if her total is $89.22?

• 10.95x + 12.57 = 89.22

• 12.57x + 10.95 = 89.22

• 89.22x - 10.95 = 12.57

• 12.57 + 10.95 = 89.22x

At Gamestop you can buy an XBox One for $150 and each game to go with it would cost $24. Or you can buy a Playstation 4 for $180 and each game cost $20. Write an equation to determine how many games (x) would need to be purchased for the cost to be the same?

• 150x + 24 = 180 + 20x

• 150 + 24x = 180 + 20x

• 180 - 150 = 24x + 20x

• 150 - 24x = 180 - 20x

Nancy went to the grocery store.  On Monday she purchased 4 apples and 6 bananas for a total of $13.  On Wednesday she purchased 3 apples and 7 bananas for a total of $13.50.  Which system of equations represents the situation? Let x be the number of apples and y be the number of bananas.

• 4x + 6y = 3
  13.5x - 13y = 6
• x + y = 4
  x - y = 6
• 4x + 6y = 13
  3x + 7y = 13.5
• 4x - 6y = 13
  3x - 7y = 13.5
