Carl is having a party on Saturday and is inviting 15 guests. He would like to make sure everyone, including himself, has at least 2 glasses of punch. Each glass holds 12 ounces of punch. How many ounces of punch does he need to buy for the party? Give me reasons, before answering the question
Including Carl, there will be 15 + 1 = 16 people at the party. Carl would like each person to be able to have 2 cups x 12 ounces = 24 ounces of punch. Carl needs to buy 16 x 24 = 384 ounces of punch. So the final answer is 384.
