Reasoning and answer: 27 * 4 = 108 yards. 2 * (12 + 9) = 42 yards. 108 + 42 = 150 yards. The playground and garden have a combined fence length of 150 yards.
The answer: 150

Question: There is a playground that is surrounded by a square fence that has a side length of 27 yards. There is a 12 yard by 9 yard garden that has fencing around it. How many yards of fencing do the playground and garden have together?
As Johnny and his son are humans, and humans walk on two legs, this means that between the two of them there are 2 * 2 = 4 legs' worth of organisms. There are two dogs walking along as well, and since dogs walk on 4 legs this means there are 2 * 4 = 8 legs' worth of organisms. We add these two totals together to find there are 4 + 8 = 12 legs' worth of organisms in total.
The answer: 12
Reverse engineering the question: Johnny is out walking his two dogs at night, and his son joins him for the walk. How many legs' worth of organisms are traveling together for this walk?
Reasoning and answer: Haley held 8 marshmallows. Michael held 3 times Haley's, so he held 8 x 3 = 24 marshmallows. Brandon held half as many marshmallows as Michael, so he held 24 / 2 = 12 marshmallows. Together, they held 8 + 24 + 12 = 44 marshmallows.
The answer: 44
What was the question?
Question: Haley, Michael and Brandon were trying a marshmallow challenge to see who could hold more marshmallows in their mouths. Haley could hold 8 marshmallows in her mouth. Michael could hold 3 times as many marshmallows as Haley. Brandon could hold half as many as Michael. How many total marshmallows did all three kids hold in their mouths?
Let x be the cost of the pencil. If the pen costs 2 times the cost of the pencil, then it costs 2x. Adding the cost of the pen and pencil we get 2x + x = 3x. Since the total cost is $6 then 3x = $6 therefore x = $6 / 3 = $2. One pen is equal to 2 * x which is 2 * $2 = $4.
The answer: 4
Reverse engineering the question: A pen and pencil have a total cost of $6. If the pen costs twice as much as the pencil, what is the cost of the pen?
Reasoning and answer: Let G stand for the number of GB billed, so the total bill is $0.25G + $45 flat rate charge = $65 total bill. Now we will solve for G. $0.25G + $45 flat rate - $45 = $65 - $45. This simplifies to $0.25G = $20. $0.25G / $0.25 = $20 / $0.25. G = 80 GB were charged on this bill.
The answer: 80

Reasoning and answer: 65% of the library books are for adults because 100 - 35 = 65. There are 160 library books in total because 104 / .65 = 160.
