Q: Zack has traveled to twice the number of countries Patrick traveled to. Patrick traveled to three times the number of countries Joseph traveled to. Joseph traveled to half the number of countries George traveled to. If George traveled to 6 countries, how many countries did Zack travel to?
A: Joseph traveled to 6 / 2 = 3 countries. Patrick traveled to 3 * 3 = 9 countries. So, Zack traveled to 2 * 9 = 18 countries. The answer is 18.

[Question]Ellie went to visit a circus with Sarah and they both got lost in the house of mirrors. They have to travel through the house of mirrors a few times before they finally get out and when they leave, they discuss how many times they've seen their own reflections. Sarah says that every time they were in the room with tall mirrors, she saw her reflection 10 times and every time they were in the room with wide mirrors, she saw her reflection 5 times. Ellie says that every time they were in the room with tall mirrors, she saw her reflection 6 times and every time they were in the room with wide mirrors she saw her reflection 3 times. They both passed through the room with tall mirrors 3 times each and they both passed through the room with wide mirrors 5 times each. In total, how many times did Sarah and Ellie see their reflections?
[Answer]In the rooms with tall mirrors, Sarah saw her reflection a total of 10 reflections * 3 passes = 30 times. In the rooms with wide mirrors, Sarah saw her reflection a total of 5 reflections * 5 passes = 25 reflections. So Sarah saw her reflection a total of 30 + 25 = 55 times. In the rooms with tall mirrors, Ellie saw her reflection a total of 6 reflections * 3 passes = 18 times. In the rooms with wide mirrors, Ellie saw her reflection a total of 3 reflections * 5 passes = 15 times. So Ellie saw her reflection a total of 18 + 15 = 33 times. Therefore, Sarah and Ellie saw their reflections a total of 55 + 33 = 88 times. The answer is 88.
Q: Chrystal’s vehicle speed is 30 miles per hour. Ascending the mountain decreases its speed by fifty percent, and descending the mountain increases its speed by twenty percent. If the distance going to the top of the mountain is 60 miles and the distance going down to the foot of the mountain is 72 miles, how many hours will Crystal have to pass the whole mountain?
A: The vehicle's speed decreases to 30 x 0.50 = 15 miles per hour when ascending to the top of the mountain. So, the total time Crystal will have to spend going to the top of the mountain is 60 / 15 = 4 hours. And the speed of the vehicle increases by 30 x 0.20 = 6 miles per hour when going down to the foot of the mountain. So, the total speed of the vehicle when going down is 30 + 6 = 36 miles per hour. Thus, Chrystal will have to spend 72 / 36 = 2 hours to descend from the mountain. Therefore, the total hours she will spend to pass the whole mountain is 4 + 2 = 6 hours. The answer is 6.
Question: A play was held in an auditorium and its ticket costs $10. An auditorium has 20 rows and each row has 10 seats. If only 3/4 of the seats were sold, how much was earned from the play?
Answer: There are 20 x 10 = 200 seats in the auditorium. Only 200 x 3 / 4 = 150 seats were sold. Hence, the earnings from the play is $10 x 150 = $1500. The answer is 1500.
Q: Max has 8 children and each of his children has the same number of children as he does except for 2 who have 5 children each. How many grandchildren does he have?
A:
Out of his 8 children, 2 have only 5 children so the rest who have 8 ( the same number as him) are 8 - 2 = 6. 6 of Max's children have 8 children each for a total of 6 * 8 = 48 grandchildren. 2 of Max's children have 5 children each for a total of 5 * 2 = 10 grandchildren. In total he has 48 + 10 = 58 grandchildren. The answer is 58.
