Q: In Professor Plum's biology class there are 40 students. Of those students, 80 percent have puppies. Of those who have puppies, 25% also have parrots. How many students have both puppies and parrots?
A: We start with the initial numbers of students, 40 and multiply that by .8 for 40 * 0.8 = 32 who own puppies. That the number of students with puppies, 32, and multiply that by .25 to find out how many own both puppies and parrots, 32 * 0.25 = 8 who own puppies and parrots. The answer is 8. The answer is 8.
Question: A family has three adults and children, both girls and boys. They went out for a family trip and prepared 3 dozen boiled eggs for the trip. Every adult got 3 eggs, and the boys each received 1 more egg than each girl since the girls had some snacks. How many boys went on the trip if the number of girls was 7 and each girl received an egg?
Answer: The total number of eggs the family had is 3 * 12 = 36 eggs. If each adult received 3 eggs, the total number of eggs they got is 3 * 3 = 9 eggs. The children shared 36 - 9 = 27 eggs. Since each girl received an egg, the boys shared 27 - 7 = 20 eggs. If each boy received 1 egg more than each girl, each received 1 + 1 = 2 eggs. The boys received 20 eggs, and if each got 2 eggs, then 20 / 2 = 10 boys went on the trip. The answer is 10.
[Question]Josie and her family went on a safari and had an exciting time watching different animals grazing and playing together. She decided to count each animal she saw and calculated their total number. She counted 80 antelopes, 34 more rabbits than antelopes, 42 fewer hyenas than the total number of antelopes and rabbits combined, 50 more wild dogs than hyenas, and the number of leopards was half the number of rabbits. What the total number of animals that Josie counted?
[Answer]The number of rabbits was 80 + 34 = 114. The total number of rabbits and antelopes is 114 + 80 = 194. The number of hyenas was 42 fewer than the combined number of antelopes and rabbits, which is 194 - 42 = 152. The number of wild dogs was 50 more than the number of hyenas, that is 152 + 50 = 202. The number of leopards is 1 / 2 * 114 = 57. The total number of animals Josie saw is 57 + 202 + 152 + 114 + 80 = 605. The answer is 605.
Q: Jake sold 10 more stuffed animals than Thor. Quincy sold ten times as many stuffed animals as Thor. If Quincy sold 200 stuffed animals, how many more stuffed animals did Quincy sell than Jake?
A: Thor sold 200 / 10 = 20 stuffed animals. Jake sold 20 + 10 = 30 stuffed animals. Quincy sold 200 - 30 = 170 more stuffed animals than Jake. The answer is 170.
Question: There are two babysitters named Mila and Agnes. Mila makes $10 an hour while Agnes makes $15 an hour. Agnes works 8 hours each week. How many hours does Mila need to work to earn as much as Agnes in a month?
Answer: The weekly salary of Agnes is $15 x 8 = $120. So in a month, Agnes earns $120 x 4 = $480. Therefore, Mila needs to work for $480 / $10 = 48 hours to earn as much as Agnes's monthly earnings. The answer is 48.
