Reasoning and answer: In five years, Angelina will be 40 years old, meaning currently she is 40 - 5 = 35 years old. Since Angelina is 35 years old right now, and she is four years older than Justin, it means Justin is 35 - 4 = 31 years old.
The answer: 31

Question: Angelina is 4 years older than Justin is now. In 5 years, Angelina will be 40 years old. Calculate the age of Justin currently.
Out of his 8 children, 2 have only 5 children so the rest who have 8 ( the same number as him) are 8 - 2 = 6. 6 of Max's children have 8 children each for a total of 6 * 8 = 48 grandchildren. 2 of Max's children have 5 children each for a total of 5 * 2 = 10 grandchildren. In total he has 48 + 10 = 58 grandchildren.
The answer: 58
Reverse engineering the question: Max has 8 children and each of his children has the same number of children as he does except for 2 who have 5 children each. How many grandchildren does he have?
Reasoning and answer: The cost of the hearing aids is $2500 * 2 = $5000. So insurance covers $5000 * .8 = $4000. That means it cost him $5000 - $4000 = $1000.
The answer: 1000

Question: John ends up damaging his hearing aids. He needs to replace both of them. They cost $2500 each. Insurance covers 80% of the cost. How much does he personally have to pay?
First find how many packages the second center processes per day: 10000 packages / day * 3 = 30000 packages / day. Then add the packages the first center processes: 30000 packages / day + 10000 packages / day = 40000 packages / day. Then multiply the number of packages by Amazon's profit per package to find Amazon's daily profit: 40000 packages / day * $0.05 / package = $2000 / day. Then multiply the daily profits by the number of days in a week to find the weekly profits: $2000 / day * 7 days / week = $14000 / week.
The answer: 14000
Reverse engineering the question: Gary manages two Amazon distribution centers. The first center processes 10000 packages per day, and the second center processes three times that volume. If Amazon makes 5 cents of profit per package, how much profit per week do the two centers make combined?
Reasoning and answer: 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: 5

Question: 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?
Reasoning and answer: It cost 2 * 1.5 = $3 a day. So it cost 3 * 30 = $90 per day. Insurance covers 90 * .4 = $36. So he pays 90 - 36 = $54 a month.
The answer: 54
