Elijah collected 45 plastic bottles and 27 aluminum cans from his neighborhood. He divided the recyclable items into 3 bags with the same number in each bag. Which equation shows how to find r, the number of recyclable items Elijah put in each bag?

• r = 45 + 27 + 3

• r = (45 + 27) $\div$ 3

• r = (45 + 27) x 3

• r = 45 + 27 - 3

Tre spent $405 on a video game player and 3 video games. He spent $336 on the video game player. Each video game was the same price. Tre subtracted $336 from $405 to find the amount he spent on the video games was $69. Which equation should Tre use to find c, the cost of each video game?

• He should use the equation 69 x 3 = c because he spent $69 on the 3 video games.

• He should use the equation 69-3 + c because he only bought 3 video games.

• He should use the equation 69 + 3 = c because he bought 3 video games.

• He should use the equation 69\div3=c

  69÷3=c

  because he bought 3 video games for a total of $69.

Cameron already had 120 tickets when Mrs. Teter gave him 24 more. He decided to share his tickets evenly between himself and five of his friends who had no tickets. How many tickets did Cameron and his five friends each have after he shared?

What equation can be used to solve this problem where t is the number of tickets Cameron and each of his friends would have?
