Come up with a question and reasoning that would justify [480] as the answer.
The question is: Hooper Bay has twice as many pounds of lobster than the two other harbors combined. If the other two harbors have 80 pounds of lobster each, how many pounds of lobster are the three harbors holding?
Reasoning: Since the other two harbors have 80 pounds of lobsters each, they have a total of 80 + 80 = 160 pounds of lobster. Since Hooper Bay has two times more lobsters than the other two harbors combined, it has 2 * 160 = 320 pounds of lobster. In total, the three harbors have 320 + 160 = 480 pounds of lobster.

Come up with a question and reasoning that would justify [3] as the answer.
The question is: Colleen is making a batch of 48 cookies. She's going to add 108 chocolate chips and one-third as many M&Ms to the whole batch. What are the average number of chocolate pieces in each cookie?
Reasoning: First find the total number of M&Ms: 108 chocolate chips / 3 chocolate chips / 1 M&M = 36 M&Ms. Then add that number to the number of chocolate chips to find the total number of pieces of chocolate: 36 M&Ms + 108 chocolate chips = 144 chocolates. Then divide the total number of chocolates by the number of cookies to find the number of pieces of chocolate per cookie: 144 chocolates / 48 cookies = 3 chocolates / cookie.

Come up with a question and reasoning that would justify [12] as the answer.
The question is: Susan had a bouquet of 3 dozen roses. She gave half to her daughter, and then placed the rest in a vase. The next day, one-third of the flowers in the vase were wilted. After removing the wilted flowers, how many flowers remained in the vase?
Reasoning: Susan had a bouquet of 3 dozen roses, which is 3 * 12 = 36 flowers. She gave half, 36 / 2 = 18, to her daughter. Then she placed her 36 - 18 = 18 remaining flowers in a vase. One - third of the 18 flowers in the vase wilted, resulting in 18 / 3 = 6 wilted flowers. After removing the wilted flowers, Susan had 18 - 6 = 12 flowers remaining in the vase.
