[Question]: 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?
[Answer]: 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 answer is 384.

[Question]: For his birthday, Geoffrey received clothes and money. His grandmother gave him 20, his aunt 25 and his uncle 30. With what he already had, he now has 125 in his wallet. He goes to a video game store and gets 3 games that cost 35 euros each. How much does he have left after this purchase?
[Answer]: Let's calculate the total price of video games: 35 X 3 / game = 105. Now let's find out how much money Geoffrey has left by subtracting his spending from his starting amount of cash: 125 - 105 = 20.
So the answer is 20.

[Question]: A cake has 8 slices and each slice contains 347 calories. A pan of brownies has 6 brownies and each slice contains 375 calories. How many more calories does the cake have?
[Answer]:
The cake has 8 slices * 347 calories = 2776 calories. The brownies have 6 slices * 375 = 2250 calories. The cake has 2776 calories - 2250 = 526 more calories.
So the answer is 526.
