Question: Kenny plans to mow lawns all summer, and then use the profits to buy video-games and books. He charges $15 per lawn. The video-games are $45 each. The books are $5 each. At the end of the summer he has mowed 35 lawns. There are 5 video-games he really wants, and then he will use the rest for books. How many books can he buy?
Answer: Kenny earns $525 because 35 x 15 = 525. He spends $225 on video games because 5 x 45 = 225. He has $300 left because 525 - 225 = 300. He can buy 60 books because 300 / 5 = 60. The answer is 60.
[Question]The time Juan takes to grab his lunch from his office and back is half the time he takes to read a book. If he has a 4000-page book, how many pages does he read in an hour if he takes 4 hours to move from his office to grab lunch?
[Answer]If Juan takes 4 hours to move from his office to grab lunch, moving from his office and back takes 2 * 4 = 8 hours. The time Juan takes to grab his lunch from his office and back is half the time he takes to read a book, meaning he reads a book in 8 * 2 = 16 hours. If he has a 4000 - page book, he will read 4000 / 16 = 250 pages in an hour. The answer is 250.
Q: Kimiko watches four YouTube videos. The first video is 2 minutes long, the second video is 4 minutes and 30 seconds, and the last two videos are equal in length. If she spends a total of 510 seconds watching YouTube, how many seconds long was each of the last two videos?
A: First convert the length of the first video to seconds: 2 minutes * 60 seconds / minute = 120 seconds. Then convert the length of the second video to seconds: 4 minutes * 60 seconds / minute + 30 seconds = 240 seconds + 30 seconds = 270 seconds. Now subtract the length of the first two videos from the total time Kimiko spent watching to find the combined length of the last two videos: 510 seconds - 120 seconds - 270 seconds = 120 seconds. Now divide the combined length by the number of videos to find each video's length: 120 seconds / 2 = 60 seconds. The answer is 60.
Question: Carmen is preparing dinner plates for a row of customers at the counter in a diner. She likes to put a couple of sprigs of parsley on each plate for decoration. However, she is very low on parsley and doesn't have enough to even put 1 sprig on every plate, so she needs to break several of the parsley sprigs in two to make 2 smaller ones to stretch them out. If she decorates 8 plates with one whole parsley sprig and 12 plates with 1/2 a sprig each, how many sprigs of parsley does she have left if she started with 25?
Answer: Carmen decorates 8 plates with 1 whole sprig of parsley, 8 plates x 1 parsley sprig each = 8 parsley sprigs. She also decorates 12 plates with 1 / 2 a sprig each, 12 x 1 / 2 = 6 parsley sprigs. She started with 25 parsley sprigs and has used 8 + 6 = 14 parsley sprigs. After using 14 parsley sprigs, she has 25 - 14 = 11 sprigs left. The answer is 11.
[Question]Ralph has $54.00 worth of products in his cart. At the register, he asks if he could have a 20% discount on an item with a small issue. This item is $20.00 to start. They agree.  Ralph also has a 10% coupon on his purchase, which he uses after the 20% discount on the item with the small issue. How much will all of his items cost?
[Answer]They approved 20% off of the $20.00 item so .20 * 20 = $4.00. The item has a $4.00 discount which can be applied from his final total of $54.00 so 54 - 4 = $50.00. Now he can use his 10% coupon on the $50.00 total so .10 * 50 = $5.00. The total was $50.00 but his $5.00 discount now makes it 50 - 5 = $45.00. The answer is 45.
