[Question]Mr Julien's store has 400 marbles remaining after the previous day's sales. Twenty customers came into the store, and each bought 15 marbles. How many marbles remain in the store?
[Answer]If each of the 20 customers bought 15 marbles, then they bought 20 * 15 = 300 marbles in total from Mr Julien's store. The number of marbles remaining in the store is 400 - 300 = 100 marbles. The answer is 100.
Q: Going into the final game, Duke is so close to breaking the school's record for most points scored in a basketball season. He only needs 17 more points to tie the record. By the end of the game, Duke breaks the record by 5 points. The old record was 257 points. In the final game Duke made 5 free throws (worth one point), and 4 regular baskets (worth two points), and some three-pointers. Normally, he scores 2 three-pointers a game. How many more three-pointers did he score in the final game compared to his normal amount?
A: Duke scored 22 points in the final game because 17 + 5 = 22. He scored 5 points of free - throws, because 5 x 1 = 5. He scored 8 points of regular baskets because 4 x 2 = 8. He made 9 points of three - pointers because 22 - 5 - 8 = 9. He scored 3 three - pointers in the final game because 9 / 3 = 3. Duke scored 1 more than normal because 3 - 2 = 1. The answer is 1.
Question: Mike and Leo have to print as many pamphlets as possible for a social gathering. Mike manages to print as fast as 600 pamphlets per hour for 9 consecutive hours. After a break, he resumes the task for another 2 hours achieving a third of the speed he was doing before. Leo, on the other hand, only works a third as many hours as Mike did before his break, but was twice as fast as Mike before he took his break. How many pamphlets do both manage to print at the end?
Answer: Mike printed before the break 600 pamphlets per hour * 9 hours = 5400 pamphlets. The working speed of Mike after the break was 600 pamphlets per hour / 3 = 200 pamphlets per hour. Mike printed after the break 200 pamphlets per hour * 2 hours = 400 pamphlets. Leo worked third of the time that Mike worked before the break, so he worked 9 hours / 3 = 3 hours. Leo worked twice as fast as Mike before his break 600 pamphlets per hour * 2 = 1200 pamphlets per hour. Leo printed 1200 pamphlets per hour * 3 hours = 3600 pamphlets. Combining the pamphlets of Leo and Mike 5400 + 400 + 3600 = 9400 pamphlets. The answer is 9400.
[Question]Reina has three times the number of counters and four times the number of marbles as Kevin. If Kevin has 40 counters and 50 marbles, calculate the number of counters and marbles that Reina has?
[Answer]If Kevin has 40 counters, and Reina has three, the number of counters Kevin has, Reina has 3 * 40 = 120 counters. Reina also has four times the number of marbles that Kevin has, meaning he has 4 * 50 = 200 marbles. In total, Reina has 120 counters + 200 marbles = 320 items. The answer is 320.
Q: A small poultry farm has 300 chickens, 200 turkeys and 80 guinea fowls. A strange, incurable disease hit the farm and every day the farmer lost 20 chickens, 8 turkeys and 5 guinea fowls. After a week, how many birds will be left in the poultry?
A: There are 300 + 200 + 80 = 580 birds in total. Every day 20 + 8 + 5 = 33 birds are lost. After a week which is 7 days, 33 * 7 = 231 birds would be lost. There would be 580 - 231 = 349 birds left in the poultry. The answer is 349.
Question: Liam is teaching art to a group of 10 students. He has 20 art kits that he hands out to the students to share, 1 art kit for 2 students. From those art kits half the students make 3 artworks each and half the students make 4 artworks each. How many artistic works does the whole class create?
Answer:
There are 10 students in Liam's art class and 1 / 2 of them make a different amount of artworks than the other half, 1 / 2 x 10 = 5 students. 5 students make 3 artworks each, 5 x 3 = 15 artworks. The other 5 students make 4 artworks each, 5 x 4 = 20 artworks. Combined, the students in the class make 15 + 20 = 35 artworks. The answer is 35.
