Q: Andy walks 50 meters from his house to school. After school, he comes back to the house and goes to the market. If he walks 140 meters in total, how many meters is the distance between the house and the market?
A: He walks 50m from home to school and walks 50m again from school to house, so he walks 50m + 50m = 100 meters. If the total distance is 140m, the distance between the house and the market is 140m - 100m = 40 meters. The answer is 40.
Question: A movie ticket for an adult costs $8, and a child's ticket costs $3. One adult is taking a group of children to the movies. She has $35. How many children can she take with her to the movies?
Answer: Let X be the number of children the adult can take with her. She has $35, so she could buy one ticket for her and the rest for the children. So she has $35 - $8 = $27 left for children. She could take $27 / $3 / child = 9 children with her. The answer is 9.
[Question]Ral is twice as old as Suri. In 3 years, Suri's current age will be 16. What is Ral's current age?
[Answer]If Suri will be 16 in 3 years, that means she is 16 - 3 = 13 years old now. Rai is twice as old as Suri, so she is 2 * 13 = 26 years old now. The answer is 26.
Q: There was only enough room for 21 people on a raft if no one wore life jackets. There were 7 fewer people who could fit on the raft if everyone wore life jackets. If 8 people on the raft needed life jackets, how many people could fit on the raft?
A: If everyone wore life jackets, only 21 - 7 = 14 people could fit on the raft. For every person less on the raft, 14 / 7 = 2 life jackets could fit. For 8 life jackets, 8 / 2 = 4 less people could fit. 21 - 4 = 17 people could fit on the raft. The answer is 17.
Question: Jack is making flower crowns out of red, pink and white daisies. There are nine times as many pink daisies as white daisies and three less than four times as many red daisies as pink daisies. If there are 6 white daisies, how many daisies are there total?
Answer: First find the total number of pink daisies: 9 * 6 daisies = 54 daisies. Then multiply that number by 4: 54 daisies * 4 = 216 daisies. Then subtract 3 to find the total number of red daisies: 216 daisies - 3 daisies = 213 daisies. Then add the number of each color of daisies to find the total number: 54 daisies + 213 daisies + 6 daisies = 273 daisies. The answer is 273.
Q: Jill spends time every day talking to her boyfriend on the phone. The first day of the week she spends 5 minutes on the phone with her boyfriend. Each of the following days she spends twice as much time talking on the phone as the day before. After the 5th day her parents take the phone away from her because she was on it too long. How much time did Jill spend talking to her boyfriend that week?
A:
Jill starts off spending 5 minutes on the phone, and the following day she spends double that 5 minutes for 5 * 2 = 10 minutes. The following day Jill spends double the previous day's total of 10 minutes on the phone, for 10 * 2 = 20 minutes. On the fourth day, Jill spends double the previous day's total of 20 minutes on the phone, for 20 * 2 = 40 minutes. On the fifth and final day, Jill spends double the previous day's total of 40 minutes on the phone, for 40 * 2 = 80 minutes. All told, Jill spends 5 + 10 + 20 + 40 + 80 = 155 minutes on the phone over 5 days. The answer is 155.
