Reasoning and answer: For the first week, her investment gain is $400 * 25% = $100. This leaves her investment with a value of $400 + $100 = $500. For the second week, her investment increased by $500 * 50% = $250. Pima's investment in Ethereum is now worth a total of $500 + $250 = $750.
The answer: 750

Question: Pima invested $400 in Ethereum. In the first week, it gained 25% in value. In the second week, it gained an additional 50% on top of the previous gain. How much is her investment worth now?


Liam sold 40 / 2 = 20 sets of oranges that cost $2.50 for each set. So, Liam earned $2.50 x 20 = $50. Claire earned $1.20 x 30 = $36. Thus, they were able to save $50 + $36 = $86 for their mother's birthday gift.
The answer: 86
Reverse engineering the question: Liam and Claire picked and sold oranges to save for their mother's birthday gift. Liam picked 40 oranges and sold them at $2.50 for 2 while Claire picked 30 oranges and sold them at $1.20 each. If all of their oranges were sold, how much are they going to save for their mother's birthday gift?


Reasoning and answer: There are 52 weeks in a year. For the first year, Thomas received 52 x 50 = $2600. In the second year, Thomas earned 9 x 30 = $270 a week. In a year, Thomas earned 52 x 270 = $14,040. The total for the two years is 14040 + 2600 = 16640. In 2 years, Thomas' weekly expenses amounted to $35 x (52 x 2) = $35 x 104 = $3640. By the end of 2 years, Thomas would have saved $16640 - $3640 = 13000. Thomas still needs $15,000 - 13000 = $2000.
The answer: 2000
What was the question?
Question: Thomas started saving for a car almost 2 years ago. For the first year, his weekly allowance was $50. In the second year, he got a job that pays $9 an hour at a coffee shop and worked 30 hours a week, so his parents discontinued his allowance. If the car he wants to buy is $15,000 and he spends $35 a week on himself, how much more money does Thomas need to buy the car by the end of the 2 years?


Justin would spend 45 minutes at dinner, 30 minutes doing homework, 30 minutes cleaning his room, 5 minutes on the trash and 10 on dishes for a total of 45 + 30 + 30 + 5 + 10 = 120. Justin knows that 60min is the same as 1 hour. He has 120 minutes of work so 120 / 60 = 2 hours. His movie comes on at 8 pm and he has 2 hours of chores so 8 - 2 = 6 pm is the latest time he could start his chores.
The answer: 6
Reverse engineering the question: Justin wanted to watch a movie that came on at 8 pm that night. His parents agreed as long as he finished his homework and chores before the movie started. He wouldn't be home until 5 pm because of baseball practice. He knew dinner would take 45 minutes, and he figured his homework would take 30 minutes to finish. He needed to clean his room, which would take 30 minutes; then take out the trash, which would take about 5 minutes; and empty the dishwasher, which would take another 10 minutes. What was the latest time that Justin could start his chores and homework to be done by 8 pm to watch his movie?


Reasoning and answer: Melanie set aside 20 x 3 / 4 = 15 brownies from each batch for a bake sale. So, there are 20 - 15 = 5 brownies that are not for bake sale from each batch. Out of the 5, 5 x 3 / 5 = 3 brownies are kept in a container from each batch. Thus, 5 - 3 = 2 brownies are given out from each batch. Therefore, a total of 2 x 10 = 20 brownies are given out from the 10 batches.
The answer: 20
What was the question?
Question: Melanie baked 10 batches of brownies, with 20 brownies in each batch. She set aside 3/4 of the brownies in each batch for a bake sale, put 3/5 of the remaining in a container, and gave out the rest. How many brownies are given out?


Reasoning and answer: First hour = 66 apples. Second hour = 66(2) = 132 apples. Third hour = 66(1 / 3) = 22 apples. Total number of apples picked 66 + 132 + 22 = 220 apples.
The answer: 220
