user: Q: Jill runs a business breeding llamas. Nine of her llamas got pregnant with 1 calf, and 5 of them got pregnant with twins. After they give birth, Jill traded 8 of the calves for 2 new adult llamas. Then she sells 1/3 of her herd at the market. How many total llamas (calves and adults) does Jill have now?
A: The number of calves that will be born as twins is 5 * 2 = 10 calves. The total number of adults and calves before the trade is 9 + 5 + 9 + 10 = 33. Jill had 33 - 8 = 25 left for trading 8 of the claves. But, she got 2 adult llamas in return, so she now has a total of 25 + 2 = 27 llamas. She then sold 27 / 3 = 9 llamas in the market. So, Jill has 27 - 9 = 18 llamas now. The answer is 18.
Question: There were 133 people at a camp. There were 33 more boys than girls. How many girls were at the camp?
Answer: If there were 33 fewer boys at camp, there would be the same number of both boys and girls or 133 - 33 = 100 people. That means that there were 100 / 2 = 50 girls at the camp. The answer is 50.
[Question]Joe sells cookies for 20% more than it costs to make them. If he sold 50 cookies and earned $60, how much do the cookies cost to make?
[Answer]He sold the cookies for $1.20 each because 60 / 50 = 1.2. They cost $1 to make because 1.2 / 1.2 = 1. The answer is 1.
Q: Walter goes to the zoo, where he spends a certain amount of time looking at the seals, eight times as long looking at the penguins, and 13 minutes looking at the elephants. If he spent 2 hours and 10 minutes at the zoo, how many minutes did he spent looking at the seals?
A: First find the number of minutes in 2 hours: 2 hours * 60 minutes / hour = 120 minutes. Then add 10 minutes to that amount to find the total number of minutes Walter spent at the zoo: 120 minutes + 10 minutes = 130 minutes. Let s be the amount of time he spends looking at the seals and p be the amount of time he spends looking at the penguins. From the problem, we know that s + p + 13 = 130 and p = 8s. Substituting the second equation into the first, we get s + 8s + 13 = 130. Combining like terms, we get 9s + 13 = 130. Subtracting 8 from both sides, we get 9s = 117. Dividing both sides by 9, we get s = 13. The answer is 13.
Question: Tim gets a manicure and tips the beautician 30%. If the manicure cost $30 how much did he pay in total?

Q: Jason is planning a parking garage that will have 12 floors. Every 3rd floor has a gate where drivers have to show ID, which takes two minutes. To get from one floor to the next, drivers have to drive 800 feet at 10 feet/second. How long, in seconds, does it take to get to the bottom of the garage from the top?
A:

assistant: First find the total number of gates someone has to pass through: 12 floors / 3 floors / gate = 4 gates. Then find the total time someone spends waiting at the gates: 4 gates * 2 minutes / gate = 8 minutes. Then convert that time to seconds: 8 minutes * 60 seconds / minute = 480 seconds. Then find the time to drive through one floor in seconds: 800 feet / 10 feet / second = 80 seconds. Then multiply the time per floor by the number of floors to find the total driving time: 80 seconds / floor * 12 floors = 960 seconds. Then add the total driving time to the total time waiting at the gates to find the total time to get to the bottom: 960 seconds + 480 seconds = 1440 seconds. The answer is 1440.
