Q: A pair of dogs are barking back and forth at each other from across the street. The poodle barks twice for every one time the terrier barks. The terrier’s owner hushes it every second time it barks. She has to say “hush” six times before the dogs stopped barking. How many times did the poodle bark?
A: The terrier barked twice as many times as it was told to hush, so it barked 6 * 2 = 12 times. The poodle barked two times for every terrier bark, so it barked 12 * 2 = 24 times. The answer is 24.
Question: John buys thank you cards. He decides to buy them for people who got him Christmas and birthday presents. He sent 20 for Christmas gifts and 15 for birthday gifts. If each card cost $2 how much did he spend on cards?
Answer: He bought 20 + 15 = 35 cards. So he spent 35 * 2 = $70. The answer is 70.
[Question]Betty and Dora started making some cupcakes at the same time. Betty makes 10 cupcakes every hour and Dora makes 8 every hour. If Betty took a two-hour break, what is the difference between the number of cupcakes they made after 5 hours?
[Answer]Dora made 8 cupcakes per hour for 5 hours for a total of 8 * 5 = 40 cupcakes. Betty took a 2 - hour break so she spent 5 - 2 = 3 hours making cupcakes. Betty made 10 cupcakes per hour for 3 hours for a total of 10 * 3 = 30 cupcakes. The difference between the number of cupcakes they made is 40 - 30 = 10 cupcakes. The answer is 10.
Q: Laura took six trips to park. On each trip, she spent 2 hours at the park and an additinal 30 minutes walking to and from the park. What percentage of the total time she took for her trips to the park did Laura spend in the park?
A: During 6 days, Laura would spend 2 * 6 = 12 hours in the park. If it takes 30 minutes (or 0.5 of an hour) walking to and from the park, then for the six trips, it would take her an additional 0.5 * 6 = 3 hours to walk to and from the park. In total, she would spend a total of 12 + 3 = 15 hours on her six trips. So, the fraction of time spent in the park would be 12 / 15 = 0.8. Thus, converting fraction to percentage, Laura spent 0.8 * 100% = 80% of her trip time at the park. The answer is 80.
Question: Mark wants to build a pyramid of soda cases that's four levels tall. Each level of the pyramid has a square base where each side is one case longer than the level above it. The top level is just one case. How many cases of soda does Mark need?
Answer: We know that the top level just has one case. Since each level has one more case per side than the level above it, the second level has sides that are 2 cases long. We can figure out how many cases we need for the second level by finding the area of a square with a side length of 2: 2 cases * 2 cases = 4 cases. The third level has three cases per side, so we need to find the area of a square with side length 3: 3 cases * 3 cases = 9 cases. The fourth level has a side length of 4, so we find its area with 4 cases * 4 cases = 16 cases. Finally, we add up the number of cases we need on each level: 1 cases + 4 cases + 9 cases + 16 cases = 30 cases. The answer is 30.
Q: Ali is collecting bottle caps. He has 125 bottle caps. He has red ones and green ones. If he has 50 red caps, what percentage of caps are green?
A:
He has 75 green caps because 125 - 50 = 75. The proportion of caps that are green is .6 because 75 / 125 = .6. The percentage that are green is 60 because .6 x 100% = 60%. The answer is 60.
