Question: Anna, Alison, and Jeff collect stamps. Anna had 37 stamps in her collection, Alison had 28 stamps in her collection, and Jeff had 31 stamps in his collection. Alison gave Anna half of her collection in exchange for a novel, and then Anna traded Jeff two bluebird stamps for one mountain stamp. How many stamps did Anna have in the end?
Answer: Alison gave Anna 1 / 2 * 28 = 28 / 2 = 14 stamps. Adding Alison’s stamps to Anna’s collection means Anna has 14 + 37 = 51 stamps. Then Anna traded Jeff 2 stamps, so she had 51 - 2 = 49 stamps. Anna got 1 stamp back in the trade, so she had 49 + 1 = 50 stamps in the end. The answer is 50.
[Question]Josh had 100 gummy bear candies. He decided to give his 3 siblings 10 candies each. Then he gave half of the remaining candies to his best friend. If he only wants to eat 16 gummy bear candies, how many candies are left to be shared with others?
[Answer]Josh gave a total of 3 x 10 = 30 candies to his siblings. He was then left with 100 - 30 = 70 candies. He gave 70 / 2 = 35 candies to his best friend. So he had 70 - 35 = 35 candies left. Since he only wants to eat 16 candies, there are still 35 - 16 = 19 candies left to be shared with others. The answer is 19.
Q: Ben's hockey team is 60% boys and the rest are girls. Half the girls are juniors and the other half are seniors. If the team has 50 players, how many junior girls are there?
A: The team is 40% girls because 100 - 60 = 40. The team has 20 girls because 50 x .4 = 20. The team has 10 junior girls because 20 / 2 = 10. The answer is 10.
Question: Eve wants to buy her 3 nieces cooking gear that's made for kids. The hand mitts cost $14.00 and the apron is $16.00. A set of 3 cooking utensils is $10.00 and a small knife is twice the amount of the utensils. The store is offering a 25% off sale on all cooking gear. How much will Eve spend on the gifts?
Answer: A small knife is twice the amount of the utensils that costs $10.00 so the knife costs 2 * 10 = $20.00. All total, each little kit will costs $14.00 for mitts, $16.00 for an apron, $10.00 for utensils and $20.00 for a knife for a total of 14 + 16 + 10 + 20 = $60.00. Each kit costs $60.00 and they are currently 25% off so that's a savings of 60 * .25 = $15.00. The kits are $60.00 and they are $15.00 off so they now cost 60 - 15 = $45.00. She needs to buy 3 kits and each kit costs $45.00 so that's 3 * 45 = $135.00. The answer is 135.

[Question]The number of short students in a class is 2/5 of the total number of students. If there are 90 tall students, and the class has 400 students, calculate the total number of students with average height.
[Answer]
The number of short students in the class is 2 / 5 * 400 = 160. The total number of short and tall students is 160 + 90 = 250. Since there are 400 students in the class, the number of students with average height is 400 - 250 = 150. The answer is 150.
