[Question]Carter has a 14-hour road trip. He wants to stop every 2 hours to stretch his legs. He also wants to make 2 additional stops for food and 3 additional stops for gas. If each pit stop takes 20 minutes, how many hours will his road trip become?
[Answer]He has a 14 - hour trip and wants to stop every 2 hours so that's 14 / 2 = 7 pit stops. He will make 7 pit stops plus 2 more for food and 3 more for gas for a total of 7 + 2 + 3 = 12 pit stops. Each pit stop will take 20 minutes and he is making 12 stops so that's 20 * 12 = 240 minutes. 60 minutes are in an hour and he's adding 240 minutes to his trip so that's 240 / 60 = 4 more hours. His trip started as 14 hours and he will add an additional 4 hours in pit stops for a total of a 14 + 4 = 18 hour long trip. The answer is 18.
Q: Andrew's dog has 12 burrs and six times as many ticks as burrs. How many foreign objects total are caught in the dog's fur?
A: First find how many burrs are caught in the dog's fur: 12 burrs * 6 ticks / burr = 72 ticks. Then add the number of burrs to find the total number objects: 72 objects + 12 objects = 84 objects. The answer is 84.
Question: In a town, there is a multi-story parking lot, which has room for 425 cars. The parking lot has 5 levels, each of the same size. How many more cars can one level fit if there are already 23 parked cars on that level?
Answer: When all levels are empty, each level can fit 425 / 5 = 85 cars. When there are already 23 parked cars on a level, there is still a place for 85 - 23 = 62 cars. The answer is 62.

Q: A movie theater has 6 screens which show movies back-to-back all day. If the movie theater is open for 8 hours, and each movie lasts 2 hours, how many movies are shown in total throughout the day?
A: Each screen shows movies all day, which means each screen shows 8 hours / day / 2 hours per movie = 4 movies / day. So in total, the movie theater shows 6 screens * 4 movies / day = 24 movies. The answer is 24.
Question: Karen packs peanut butter sandwiches in her daughter's lunch 2 randomly chosen days of the week. The other 3 school days, she packs a ham sandwich. She packs a piece of cake on one randomly chosen day and cookies the other four days. What is the probability, expressed as a percentage, that Karen packs a ham sandwich and cake on the same day?

There are 5 school days in a week, so the probability Karen packs a ham sandwich is 3 / 5 and the probability she packs cake is 1 / 5. Multiply the two probabilities to find the probability both things happen: 3 / 5 * 1 / 5 = 3 / 25. Now divide 3 by 25 and multiply by 100% to express this probability as a percentage: 3 / 25 * 100% = 12%. The answer is 12.
