Q: Annie goes to school. Today is her birthday, so Annie decided to buy some sweets for her colleagues. Every classmate got 2 candies. In the end, Annie got left with 12 candies. If there are 35 people in Annie's class in total, how much did Annie spend on candies, if one candy costs $0.1?
A: There are 35 people in Annie's class, which means, she has 35 - 1 = 34 classmates. Every classmate got 2 candies, so in total Annie gave out 34 * 2 = 68 candies. In the beginning she had 68 + 12 = 80 candies. One candy costs $0.1, so Annie spend 80 * 0.1 = $8 on candies. The answer is 8.
Question: Brinley's teacher took the grade six students to the San Diego Zoo to watch and learn about animals. While at the zoo, Brinley counted 100 snakes, 80 arctic foxes, and 20 leopards. She also saw ten times more bee-eaters than leopards, half as many cheetahs as snakes, and twice as many alligators as the total number of Arctic foxes and leopards. What's the total number of animals Brinley counted at the zoo?
Answer: There were 10 * 20 = 200 more bee - eaters at the zoo. There were 1 / 2 * 100 = 50 cheetahs. The total number of foxes and leopards is 80 + 20 = 100. There were 2 * 100 = 200 alligators. The total number of animals is 200 alligators + 220 bee - eaters + 100 snakes + 80 tactic foxes + 20 leopards + 50 cheetahs = 670 animals. The answer is 670.
