Question: Jake is from a conservative household so during lunch at school one day, he gave one-quarter of his feeding allowance to a hungry friend. If candies cost 20 cents apiece and Jake's feeding allowance is $4, how many candies can his friend purchase with the money Jake gave to him?
Answer: One quarter of $4 is (1 / 4) * $4 = $1. $1 is equivalent to 100 cents. 20 cents will buy 1 candy so 100 cents will buy 100 / 20 = 5 candies. The answer is 5.

[Answer]Randy has only half as many water balloons as Janice's 6, for a total of () * 6 = 3 water balloons. Cynthia has 4 times as many water balloons as Randy, for a total of 4 * 3 = 12 water balloons. The answer is 12.
Q: Adam has 50 balls. 20 balls are red, 10 are blue, and the rest are either pink or orange. If there are 3 times as many pink as orange balls, how many orange balls are there?
A: Adam has a total of 50 balls - 20 red - 10 blue = 20 pink and orange balls combined. If we let x be the total number of orange balls, we know that 3x is the number of pink balls. Therefore, 20 balls = x + 3x = 4x. The number of orange balls, x, is 20 balls / 4 = 5 balls. The answer is 5.
Question: Missy has an obedient dog and a stubborn dog. She has to yell at the stubborn dog four times for every one time she yells at the obedient dog. If she yells at the obedient dog 12 times, how many times does she yell at both dogs combined?

Q: Two vampires have come to the sleepy village of Willowton, population 300. Every night, each vampire turns 5 more people into vampires. How many vampires are there after two nights?
A:
First find the number of new vampires after one night: 5 people / vampire * 2 vampires = 10 people. Add that to the starting number of vampires to find the total number of vampires after one night: 10 vampires + 2 vampires = 12 vampires. Then find the number of new vampires on the second night: 5 people / vampire * 12 vampires = 60 people. Add that number to the starting number of vampires on the second night to find the total number of vampires after two nights: 60 vampires + 12 vampires = 72 vampires. The answer is 72.
