[Question]A factory decides to stop making cars and start making motorcycles instead. When it made cars, per month, it cost $100 for materials, they could make 4 cars, and they sold each car for $50. Now that they make motorcycles it costs $250 for materials, but they sell 8 of them for $50 each. How much more profit do they make per month selling motorcycles instead of cars?
[Answer]They sold $200 worth of cars each month because 4 x 50 = 200. They made $100 a month off cars because 200 - 100 = 100. They sold $400 worth of motorcycles each month because 8 x 50 = 400. They make $150 a month off motorcycles because 400 - 250 = 150. They make $50 more a month off motorcycles than cars because 150 - 100 = 50. The answer is 50.
Q: Jerry can run from his house to his school and back in the time it takes his brother Carson to run to the school. If it takes Jerry 15 minutes to make a one-way trip from his house to his school and the school is 4 miles away, how fast does Carson run in miles per hour?
A: We know that Carson takes twice as long as Jerry to get to the school, so we can find the time it takes him by multiplying Jerry's time by 2: 15 minutes * 2 = 30 minutes. Then convert that time to house by dividing by 60 minutes / hour = 30 minutes / 60 minutes / hour = .5 hour. Then divide the distance Carson runs by the time it takes him to run it to find his speed: 4 miles / 0.5 hours = 8 miles / hour. The answer is 8.
Question: Harry is 50 years old. His father is currently 24 years older than he is. How old was his mother when she gave birth to him if she is younger than his father by 1/25 of Harry's current age?
Answer: Harry's father is 50 years + 24 years = 74 years old. Harry's mother is 1 / 25 * 50 years = 2 years younger than his father. So she is currently 74 years - 2 years = 72 years old. So when Harry was born, she was 72 years - 50 years = 22 years old. The answer is 22.
[Question]Matthew asked his children how many hotdogs they wanted for dinner. Both Ella and Emma agreed they wanted 2 hotdogs each. Luke said he could eat twice the amount of hotdogs as his sisters while Hunter said he could only eat 1 and half times the total amount of his sisters. How many hotdogs did Matthew need to cook?
[Answer]Ella wanted 2 while Emma wanted 2 so 2 + 2 = 4 hotdogs. Luke could eat twice as his sisters so 2 * 2 = 4 hotdogs. Hunter could eat 1 1 / 2 times the amount of his sisters so 1.5 * 4 = 6 hotdogs. All total, Matthew needs to cook, 4 + 4 + 6 = 18 hot dogs. The answer is 14.
Q: A fisherman catches 3 types of fish in his net. There are 32 bass, 1/4 as many trout as bass, and double the number of blue gill as bass. How many fish did the fisherman catch total?

Question: You start a business selling charm bracelets. You spend $1 on the string for each bracelet and $3 on beads for each bracelet. You sell the bracelets for $6 each. If you sell 25 bracelets, how much profit will you make?
