Question: Nancy carves statues out of jade. A giraffe statue takes 120 grams of jade and sells for $150. An elephant statue takes twice as much jade and sells for $350. If Nancy has 1920 grams of jade, how much more money will she make turning it all into elephants instead of giraffes?
Answer: First find how many giraffe statues Nancy can make by dividing the total amount of jade by the amount used per giraffe statue: 1920 g / 120 g / giraffe = 16 giraffes. Then multiply that number by the price per giraffe to find how much Nancy earns total from giraffes: 16 giraffes * $150 / giraffe = $2400. Then find how much jade each elephant statue uses by doubling the jade used by the giraffe statues: 120 g / giraffe * 2 = 240 g / elephant. Then find how many elephant statues Nancy can make by dividing the total amount of jade by the amount used per elephant statue: 1920 g / 240 g / elephant = 8 elephant. Multiply that number by the price per elephant to find Nancy's total earnings from elephants: 8 elephants * $350 / elephant = $2800. Finally, subtract Nancy's total earnings from the giraffes from her total earnings from the elephants to find the difference: $2800 - $2400 = $400. The answer is 400.

Q: At school today, Charlize was 20 minutes late. Four of her classmates were each ten minutes late than she was. What's the total time for which the five students were late?
A: If Charlize was 20 minutes late, each of her friends was 20 + 10 = 30 minutes late. The total time for which Charlize's friends were late was 4 * 30 = 120 minutes. Together with Charlize, the three friends were 120 + 20 = 140 minutes late. The answer is 140.
Question: Two-thirds of all the animals on my street are cats and the rest are dogs. If there are 300 animals on the street, what's the total number of legs of dogs that are on the street?
Answer: The number of cats on the street is 2 / 3 * 300 = 200. If there are 300 animals on the street, and 200 are cats, there are 300 - 200 = 100 dogs. Since a dog has four legs, the total number of legs the 100 dogs have is 100 * 4 = 400 legs. The answer is 400.
[Question]Theo can eat 13 cookies, 3 times a day, 20 days each month. How many cookies can he eat in 3 months?

[Question]John receives $100 from his uncle and gives his sister Jenna 1/4 of that money. He goes and buys groceries worth $40. How much money does John have remaining?
[Answer]
When John gives his sister 1 / 4 of his money, he parts with 1 / 4 * 100 = 25 dollars. Johns remains with 100 - 25 = 75 dollars. When he buys groceries worth $40, he remains with 75 - 40 = 35 dollars. The answer is 35.
