[Question]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?
[Answer]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.
Q: Samanta is planning a party for her friend Marta. She decided to raise some money among the guests she invited, to buy Marta a gift. Every participant gave Samanta $5 for this purpose and she herself put in $10. The gift cost was lower than expected, so there was $15 leftover. What was the price of the gift, if there were 12 guests invited?
A: From all the guests Samanta got $5 / guest * 12 guests = $60. Including money Samanta put herself, she had $60 + $10 = $70. The cost of the gift was $70 - $15 = $55. The answer is 55.

[Question]A leaf is being blown down a sidewalk by swirling gusts of wind. For every five feet that a gust blows it forward, the wind swirls and blows it back two feet. How many feet has it traveled down the sidewalk after 11 gusts of wind?
[Answer]Each gust blows the leaf forward 5 feet, so 11 gusts will blow it forward 5 * 11 = 55 feet. Each swirl after a gust blows it back 2 feet, so 11 swirls will blow it back 2 * 11 = 22 feet. After 11 gusts, the leaf has traveled 55 - 22 = 33 feet down the sidewalk. The answer is 33.
Q: Lake Crystal has twenty percent fewer frogs than Lassie Lake. If Lassie Lake has forty-five frogs, how many frogs are there in total in the two lakes?
A: Lake Crystal has twenty percent fewer frogs than Lassie Lake, a total of 20 / 100 * 45 = 9 frogs. The total number of frogs in Lake Crystal is 45 - 9 = 36. Together, the two lakes have 36 + 45 = 81 frogs. The answer is 81.
Question: A watermelon stand sold 46 watermelons. Seventeen customers bought one melon, three customers bought three melons, and the rest bought two melons. How many customers bought two watermelons?
Answer:
The customers that bought one watermelon bought 1 * 17 = 17 melons. The customers that bought three melons bought 3 * 3 = 9 melons. The stand sold 46 - 17 - 9 = 20 melons to customers who bought 2 melons. Thus, 20 / 2 = 10 customers bought two watermelons. The answer is 10.
