Question: John has started at a job he works every day 10 days ago. So far, he's made $250. How many more days must John work before he makes twice this amount, assuming he makes the same amount every day?
Answer: John has made $250 in 10 days, so this means he makes $250 / 10 = 25 dollars a day. Since John wants to make double his current amount, this means he wants to make 250 * 2 = 500 dollars. This means John needs to work 500 / 25 = 20 days in total to make 500. As John has already worked 10 days, this means he needs to work 20 - 10 = 10 more days to make his goal. The answer is 10.
[Question]Stan hires a magician for $60 an hour. He works 3 hours every day for 2 weeks. How much money does he pay the magician?

Q: A vendor at the market is selling sunglasses for $30 each. He has to spend a certain amount to buy these sunglasses. He sells 10 pairs in a day. He then takes half his profits and uses it to buy a new sign, which costs $20. How much does each pair of sunglasses cost him to buy?
A: His profits were $40 because 20 / .5 = 40. He made $300 selling sunglasses because 10 x 30 = 300. His costs for the sunglasses were $260 because 300 - 40 = 260. The sunglasses cost him $26 each because 260 / 10 = 26. The answer is 26.
Question: Milly is making croissants. She needs to fold the dough 4 times, which takes 5 minutes each time, then let it rest for 75 minutes each time. If mixing the ingredients takes 10 minutes and baking the croissants takes 30 minutes, how many hours does the whole process take?
Answer: First finding the time to fold the dough and let it rest one time: 5 minutes + 75 minutes = 80 minutes. Then find the total time spent folding and resting the dough: 80 minutes / time * 4 times = 320 minutes. Then add the mixing and baking time: 320 minutes + 30 minutes + 10 minutes = 360 minutes. Then divide that number by the number of minutes per hour to find the total time in hours: 360 minutes / 60 minutes / hour = 6 hours. The answer is 6.
[Question]A man divides 3 hectares of land evenly among his 8 sons. If every 750m^2 of this land can be used to make a profit of $500 from every 3 months of commercial farming, how much can each son make if they cultivate their share of the land for one year(1 hectare is equal to 10000 m^2)?
[Answer]There are 10000m^2 in each hectare, so 3 hectares contains 3 * 10000 = 30000m^2 of land. 30000m^2 is divided among 8 sons so each son will get 30000 / 8 = 3750m^2. In every 3750m^2, there are 3750 / 750 = 5 portions of 750m^2 areas of land. Each son can make 5 * $500 = $2500 every 3 months from cultivating their share. In one year there are 12 months so each son can make $2500 up to 12 / 3 = 4 times in a year. Each son can make a total of $2500 * 4 = $10000 in a year. The answer is 10000.
[Question]There are 14 girls, 11 boys, and their parents at a park. If they split into 3 equally sized playgroups, each group contains 25 people. How many parents were at the park?
