Uncle Freddy rented a total of 12 movies and games. A movie rents for $3 and a game rents for $4.50, for a total of $42. There are 3 times as many movies than games. Which system models this scenario?

• 3M + 4.50G = 42

  M + G = 12

  M = 3G

• 3M + 4.50G = 12

  M + G = 42

  3M = G

• M + G = 12

  4.50M + 3G = 42

  3M = G
