Reasoning and answer: The temperature dropped 1.8 degrees because 80 - 78.2 = 1.8. She planted 18 trees because 1.8 / .1 = 18. It cost $108 to plant the trees because 18 x 6 = 108.
The answer: 108

Question: Sasha heard that planting trees helps to reduce the local temperature. For each tree planted, the temperature drops .1 degree. A tree costs $6 to plant. If she got the local temperature to drop from 80 to 78.2, how much did it cost to plant the trees?
The cost of the 200 employees is 200 employees * $12 / employee / hour = $2400 per hour. The cost of the 40 employees is 40 employees * $14 / employee / hour = $560 per hour. The rest means 300 employees - 200 employees - 40 employees = 60 employees. These 60 employees' employment costs are at 60 employees * $17 / employee / hour = $1020 per hour. So in total all employees earn $2400 / hour + $560 / hour + $1020 / hour = $3980 / hour. During an 8 - hour shift, this cost would be at 8 hours * $3980 / hour = $31840.
The answer: 31840
Reverse engineering the question: In a factory, there are 300 employees. 200 of them earn $12 per hour. Of the rest, 40 of them earn $14 per hour. All others earn $17 per hour. What is the cost to employ all these people for one 8-hour long shift?
Reasoning and answer: Ben has 26 - 9 = 17 dollars. Eric has 17 - 10 = 7 dollars. They have 26 + 17 + 7 = 50 dollars in total.
The answer: 50

Question: Eric, Ben, and Jack have some money. Eric has $10 less than Ben, and Ben has $9 less than Jack. If Jack has $26, how much money, in dollars, do all 3 of them have in total?
2 tattoos on each arm is a total of 2 * 2 = 4 tattoos. 3 tattoos on each leg is a total of 2 * 3 = 6 tattoos. Thus, Jason has 4 + 6 = 10 tattoos. Twice the number of tattoos that Jason has is 2 * 10 = 20 tattoos. Adam has 3 more than twice the number Jason has, or 3 + 20 = 23 tattoos.
The answer: 23
Reverse engineering the question: Adam has three more than twice as many tattoos as Jason has. If Jason has two tattoos on each of his arms and three tattoos on each of his legs, how many tattoos does Adam have?
Reasoning and answer: First find how many hours he spends studying by dividing the number of hours spent gaming by 3: 9 hours / 3 = 3 hours. Then multiply that quantity by the point increase per hour to find Jackson's grade: 3 hours * 15 points / hour = 45 points.
The answer: 45

Question: Jackson spends 9 hours playing video games and 1/3 that much time studying. If Jackson's grade starts at 0 points and increases by 15 points for every hour he spends studying, what is his grade?
Reasoning and answer: First find how many degrees below 32 the temperature is: 32 degrees - 8 degrees = 24 degrees. Then divide that amount by the number of degrees per 5% increase in skid risk to find how many 5% increases there are: 24 degrees / 3 degrees / 5% increase = 8 5% increases. Multiply the number of increases by 5% to find the total increase in skid risk: 8 * 5% = 40%. Now find the chance that Annie has a serious accident if she goes into a skid by subtracting the chance she regains control from 100%: 100% - 40% = 60%. Finally, multiply the chance of going into a skid by the chance of having a serious accident after a skid to find the total risk of a serious accident: 60% * 40% = 24%.
The answer: 24

Question:
Annie is trying to figure out whether it's safe to drive her truck. For every 3 degrees the temperature drops below 32 degrees, Annie's chances of skidding on ice increase 5%. If she goes into a skid, she has a 40% of regaining control. Otherwise, she'll have a serious accident. If the temperature is 8 degrees, what is the percentage chance of Annie getting into a serious accident if she drives?
