[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.
Q: Josh built his little brother a rectangular sandbox. The perimeter of the sandbox is 30 feet and the length is twice the width. What is the width of the sandbox?
A: There are four sides to a rectangle, the width is W and so the length is 2W, and we can put that in this equation: W + W + 2W + 2W = 30 feet. If we add the sides together, we get 6W = 30 feet. To find W, we divide both sides by 6, like this: 6W / 6 = 30 feet / 6, so W = 5 feet. The answer is 5.
