Question: The ratio of books to pens that Arlo has to buy for his school supplies is 7:3. If he bought a total of 400 stationery from the store, calculate the number of books he bought.
Answer: The total ratio representing the stationery that Arlo has to buy for his school supplies is 7 + 3 = 10. The fraction representing the number of books that Arlo bought is 7 / 10, and since he bought a total of 400 books and pens, he bought 7 / 10 * 400 = 280 books. The answer is 280.
[Question]On the weekend, Tony will walk to the store. On weekdays, he runs to the store. When he walks, he goes 2 MPH. When he runs he goes 10 MPH. The store is 4 miles away. If he goes on Sunday, Tuesday, and Thursday, what is the average time in minutes that he spends to get to the store?
[Answer]On Sunday he takes 2 hours to get there because 4 / 2 = 2. This takes him 120 minutes because 2 x 60 = 120. On Tuesday and Thursday, it takes him .4 hours to get to the store because 4 / 10 = .4. On Tuesday and Thursday, it takes him 24 minutes to get to the store because .4 x 60 = 24. In total it takes him 168 minutes to get to the store because 120 + 24 + 24 = 168. On average it takes him 56 minutes because 168 / 3 = 56. The answer is 56.
Q: John has 25 horses. He feeds each horse twice a day and feeds them 20 pounds of food at each feeding. He buys half ton bags of food. How many of those will he have to buy in 60 days?
A: He feeds each horse 2 * 20 = 40 pounds of food a day. So he uses 40 * 25 = 1000 pounds of food a day. That means in 60 days he uses 60 * 1000 = 60000 pounds of food. Each bag of food is 2000 * .5 = 1000 pounds. So he needs to buy 60000 / 1000 = 60 bags of food. The answer is 60.
Question: Mr. Doré bought $140 worth of pants, a $43 shirt and a $15 tie. He pays with a $200 bill. How much will the saleswoman give him back?
