[Question]A farmer living in the countryside has a certain number of children. One day, they followed him to the farm, each one with a bag to collect harvested apples. At the end of the day, each bag was filled with 15 apples each. On their way back home, 2 of the children have eaten 4 apples each and another child sold 7 of his apples. If they had a total of 60 apples left by the time they got home, how many children does the farmer have?
[Answer]2 children sold 4 apples each which gives 2 * 4 = 8 apples. Another child gave out an additional 7 apples making 8 + 7 = 15 apples removed from the total. There were 60 apples left after these, so the original total must have been 15 + 60 = 75 apples. Each child collected 15 apples so there are 75 / 15 = 5 children. The answer is 5.
Q: Carol spends five hours filling up her pool. During the first hour, the pool fills at a rate of 8 gallons of water per hour. For the next two hours, the pool fills at 10 gallons of water per hour. For the fourth hour, the pool fills at a rate of 14 gallons of water per hour. During the fifth hour, the pool develops a leak and loses 8 gallons of water. At the end of five hours, how many gallons of water are still left in the pool?
A: 8 gallons of water added during the first hour. 10 gallons of water added during the second hour. 10 gallons of water added during the third hour. 14 gallons of water added during the fourth hour. The total gallons of water added by the fourth hour is 8 + 10 + 10 + 14 = 42. The number of gallons in the pool after losing 8 gallons in the fifth hour is 42 - 8 = 34. The answer is 34.
Question: Janet needs 5 tickets to ride the roller coaster and 3 tickets to ride the giant slide. How many tickets does she need to ride the roller coaster 7 times and the giant slide 4 times?
Answer: First find how many tickets she needs for the roller coaster: 5 tickets / ride * 7 rides = 35 tickets. Then find how many tickets she needs for the giant slide: 3 tickets / ride * 4 rides = 12 tickets. Then add the number of tickets she needs for each ride to find the total number of tickets she needs: 12 tickets + 35 tickets = 47 tickets. The answer is 47.
[Question]A baker is comparing the day's sales to his daily average. He usually sells 20 pastries and 10 loaves of bread. Today, he sells 14 pastries and 25 loaves of bread. If pastries are sold for $2 and loaves of bread are sold for $4, what is the difference, in dollars, between the baker's daily average and total for today?
[Answer]The daily average sales of pastries amounts to 20 pastries * $2 / pastry = $40. The daily average sales of bread amounts to 10 loaves of bread * $4 / loaf = $40. Therefore, the daily average is $40 + $40 = $80. Today's sales of pastries amounts to 14 pastries * $2 / pastry = $28. Today's sales of loaves of bread amounts to 25 loaves of bread * $4 / loaf = $100. Therefore, today's sales amount to $28 + $100 = $128. This means the total difference between today's sales and the daily average is $128 $80 = $48. The answer is 48.
Q: Ella has 4 bags with 20 apples in each bag and six bags with 25 apples in each bag. If Ella sells 200 apples, how many apples does Ella has left?
A: 4 bags have 4 x 20 = 80 apples. And, six bags have 6 x 25 = 150 apples. Thus, Ella has 80 + 150 = 230 apples in all. Therefore, Ella has 230 - 200 = 30 apple left. The answer is 30.
