Question: CJ, KJ, and AJ collect stamps. CJ has 5 more than twice the number of stamps that KJ has, and KJ has half as many as AJ. If the three boys have 930 stamps all together, how many stamps does AJ have?
Answer: Let x represent the number of stamps for AJ. KJ:x / 2 stamps. CJ:5 + 2(x / 2) = 5 + x. Total:x + (x / 2) + 5 + x = 930. (5 / 2)x + 5 = 930. (5 / 2)x = 925. x = 925(2 / 5) = 370 stamps. The answer is 370.
[Question]In a Math competition, Sammy scored 20 points, Gab scored twice as many as Sammy's score, while Cher scored twice as many as Gab's score. If their opponent scored 85 points, how many more points do they have than their opponent?
[Answer]Gab scored 20 x 2 = 40 points. Cher scored 40 x 2 = 80 points. Their team scored 20 + 40 + 80 = 140 points. Therefore, they scored 140 - 85 = 55 more points than their opponent. The answer is 55.
Q: Irene shares half of a small apple with her dog every day. A small apple weighs about 1/4 of a pound. She can currently buy apples for $2.00 a pound. How much will she spend so that she and her dog have enough apples to last for 2 weeks?
A: There are 7 days in a week and she needs apples for 2 weeks so that's 7 * 2 = 14 days. She shares an apple with her dog every day so for 14 days so she needs 1 * 14 = 14 apples. Each apple weighs 1 / 4 of a pound and she needs 14 apples so that's .25 * 14 = 3.5 pounds of apples. She needs 3.5 pounds of apples and they are on sale for $2.00 a pound so she will spend 3.5 * 2 = $7.00 for apples. The answer is 7.
Question: Samuel is going to the cinema with his brother, Kevin. They both have a total budget of $20 for their outing. Samuel buys his $14 ticket, then spends $6 on drinks and food. Kevin buys his ticket, then spends $2 on drinks. They have both used their entire budget. How much did Kevin spend on food?
Answer: We know Kevin bought a ticket and drinks, and this cost him 14 + 2 = 16 dollars. Since Kevin spent his entire budget, his food must have cost 20 16 = 4 dollars. The answer is 4.
[Question]To finish the task assigned to her by the work supervisor in the stipulated deadline, Anie needs 5 hours extra aside from the normal work schedule each day. If each day her work schedule requires her to be productive for 10 hours, and the project is estimated to take 1500 hours, calculate the number of days it would take Anie to finish the job.
[Answer]Every day, in addition to her 10 - hour work schedule, Anie needs 5 extra hours, which means she works 10 + 5 = 15 hours each day. If the project is estimated to take 1500 hours, Anie will need to work for 1500 / 15 = 100 days to complete the project. The answer is 100.
