[Question]Jan is making candy necklaces for herself and a few friends. Everyone receives a candy necklace each and each candy necklace is made up of 10 pieces of candies. The pieces of candies come from blocks of candy, which each produce 30 pieces of candy. If Jan breaks down 3 blocks of candy and every single piece of candy from this is used in the candy necklaces, how many friends receive a candy necklace?
[Answer]There are a total of 3 blocks of candy * 30 pieces of candy per candy block = 90 pieces of candy. Using this, Jan can create 90 pieces of candy / 10 pieces of candy per candy necklace = 9 candy necklaces. As Jan is keeping a candy necklace too, there must have been enough candy necklaces for 9 candy necklaces – 1 candy necklace for Jan = 8 friends. The answer is 8.

[Question]The Reptile House at the zoo has 5 fewer animals than 3 times the number of animals housed in the Rain Forest exhibit. If the Reptile House has 16 animals, how many are in the Rain Forest exhibit?

[Question]There are 92 students altogether. Twenty of them ride the school bus home together, 5/8 of the remaining ride their own bike home, and the rest whose houses are near the school walk home. How many students are walking home?
[Answer]If there are 92 students and 20 students take the bus home, the number of students who haven't taken the bus is 92 - 20 = 72 students. 5 / 8 of the students who didn't take the bus home ride bikes home, a total of 5 / 8 * 72 = 45 students. The number of students who neither took the bus nor biked home but walked home is 72 - 45 = 27. The answer is 27.

[Question]In my school, the number of students has increased by 20% this year. The number of students this year is 960. How many students were there last year?
[Answer]
Let X be the number of students last year. The number of students this year is X + X * 20% = 960. Combining like terms, we get X * 1.2 = 960. Dividing both sides by 1.2, we get X = 800 students. The answer is 800.
