Phil and Andre decide to order some pizza. They get a small cheese and a large pepperoni. The small pizza has 8 slices, The large has 14 slices. They have both eaten 9 slices already. How many pieces are left per person? Give the rationale and then the answer.
Let's think step by step. There are 22 pieces of pizza because 14 plus 8 equals 22. They have eaten 18 pieces of pizza because 9 plus 9 equals 18. There are 4 pieces of pizza left because 22 minus 18 equals 4. There are 2 pieces per person because 4 divided by 2 equals 2.. The answer is: 2.

Toby has 63 photos on his camera roll. He deletes seven bad shots, takes fifteen pictures of his cat, and then does a photo shoot with his friends. After editing the photos with his friends, he decides to delete three of them. His camera roll has 84 photos in the end. How many photos did Toby take in the photo shoot? Give the rationale and then the answer.
Let's think step by step. Let P be the number of photos in the photo shoot. After Toby deleted 7 shots, he had 63 - 7 = 56 photos. After taking 15 cat pictures, he had 56 + 15 = 71 photos. After the photo shoot, he had 71 + P photos. After deleting 3 photos, he had 71 + P - 3 = 68 + P photos. He had 68 + P = 84 photos in the end. Thus, Toby took P = 84 - 68 = 16 photos in the photo shoot.. The answer is: 16.
