[Question]Mandy has three $20 bills while Manny has two $50 bills. If both of them decide to exchange their bills for $10 bills, how many more $10 bills than Mandy will Manny have?
[Answer]Mandy has a total of $20 x 3 = $60. So, she will have $60 / $10 = 6 $10 bills. Manny has a total of $50 x 2 = $100. So, he will have $100 / $10 = 10 $10 bills. Hence, Manny has 10 - 6 = 4 more $10 bills than Mandy. The answer is 4.
Q: A farmer plants his vegetables in neat rows. He has 64 bean seedlings and plants 8 seedlings in a row. He also has 84 pumpkin seeds and plants 7 seeds in a row. Recently, he planted 48 radishes with 6 radishes in a row. If the farmer plants two rows per plant bed, how many plant beds did he have for all his plants?
A: There are 64 / 8 = 8 rows of bean seedlings. There are 84 / 7 = 12 rows of pumpkin seedlings. There are 48 / 6 = 8 rows of radishes. Thus, there are a total of 8 + 12 + 8 = 28 rows of vegetables. Therefore, the farmer had 28 / 2 = 14 plant beds. The answer is 14.
Question: Andy is making fudge. First he needs to raise the temperature of the candy mixture from 60 degrees to 240 degrees. Then he needs to cool it down to 170 degrees. If the candy heats at 5 degrees/minute and cools at 7 degrees/minute, how long will it take for the candy to be done (in minutes)?
Answer: First find the total number of degrees the candy needs to heat up: 240 degrees - 60 degrees = 180 degrees. Then divide that amount by the rate the candy heats up: 180 degrees / 5 degrees / minute = 36 minutes. Then find the number of degrees the candy needs to cool down: 240 degrees - 170 degrees = 70 degrees. Then divide that by the rate the candy cool down: 70 degrees / 7 degrees / minute = 10 minutes. Then add the time for the candy to heat to the time for it to cool to find the total time: 10 minutes + 36 minutes = 46 minutes. The answer is 46.
[Question]The average speed for an hour drive is 66 miles per hour. If Felix wanted to drive twice as fast for 4 hours, how many miles will he cover?
[Answer]If Felix drives twice as fast, he will be covering 2 * 66 = 132 miles per hour. In four hours, driving at 132 miles per hour, since distance = speed * time, Felix will cover 132 * 4 = 528 miles. The answer is 528.
Q: DeShaun always wins the award in English class for reading the most books over the summer. This year is no different. Summer break is 80 days long. When he arrives, he notifies the teacher that he read 60 books over the summer. Each book averaged 320 pages long. The person closest to him read 75% as much as he did. How many pages did the second person read on average each day of break?
A: Deshaun read 19,200 pages because 60 x 320 = 19,200. The person closest to him read 14, 400 pages because 19,200 x .75 = 14,400. They read 180 pages a day because 14, 400 / 80 = 180. The answer is 180.
Question: Remy sold 55 bottles of soda in the morning. Nick sold six fewer bottles of soda than Remy. The price per bottle is $.50. If their total evening sales are $55, how much more did they earn in the evening than in the morning?
Answer:
Nick sold 55 - 6 = 49 bottles of soda in the morning. They sold 55 + 49 = 104 bottles of soda altogether. They earned a total of 104 x $.50 = $52 in the morning. So, they earned $55 - $52 = $3 more in the evening than in the morning. The answer is 3.
