[Question]A snack machine accepts only quarters. Candy bars cost 25, each piece of chocolate costs 75, and a pack of juice costs 50. How many quarters are needed to buy three candy bars, two pieces of chocolate, and one pack of juice?
[Answer]Three candy bars cost 25 x 3 = 75. Two pieces of chocolate cost 75 x 2 = 150. So, the total amount needed to buy those is 75 + 150 + 50 = 275. Since a quarter is equal to 25, therefore 275 / 25 = 11 quarters are needed. The answer is 11.
Q: Martiza is studying for the citizenship test. There are 60 questions on the test. 30 are multiple-choice and 30 are fill-in-the-blank. It takes her 15 minutes to learn each multiple-choice question and 25 minutes each to learn the fill-in-the-blank questions. How many hours will she need to study before she is ready for the test?
A: The multiple - choice questions will take her a total of 30 * 15 = 450 minutes. The fill - in - the - blank questions will take her a total of 25 * 30 = 750 minutes. The test will take her a total of 450 + 750 = 1200 minutes to study for. Therefore, Martiza will need to study a total of 1200 / 60 minutes = 20 hours. The answer is 20.

[Question]Mr. Reyansh has a dairy farm with 40 cows. Each cow on the farm drinks 80 liters of water daily. He also has a sheep ranch with 10 times the number of cows, with each sheep drinking 1/4 times as much water as a cow does. How many liters of water does Mr. Reyansh use to water all of his animals in a week?
[Answer]If a cow drinks 80 liters of water in a day, it drinks 80 * 7 = 560 liters of water per week. Mr. Reyansh has 40 cows drinking 560 liters of water a week, totaling 560 * 40 = 22400 liters. In the ranch, a sheep drinks 1 / 4 * 80 = 20 liters of water in a day. The total amount of liters a sheep drinks in a week is 20 * 7 = 140 liters. Mr. Reyansh has ten times as many sheep as cows, that is 10 * 40 = 400 sheep. If each sheep drinks 140 liters of water in a week, 400 sheep drinks 400 * 140 = 56000 liters of water. Together, the cows and sheep drink 56000 + 22400 = 78400 liters of water per week. The answer is 78400.
Q: Burt spent $2.00 on a packet of basil seeds and $8.00 on potting soil. The packet of seeds yielded 20 basil plants. He sells each basil plant for $5.00 at the local farmer's market. What is the net profit from his basil plants?
A: He spent $2.00 on seeds and $8.00 on soil for a total of 2 + 8 = $10.00. He sells each of the 20 basil plants for $5.00 so he makes 20 * 5 = $100.00. He made $100.00 from selling basil plants and he spent $10.00 to buy and grow the seeds. His net profit is 100 - 10 = $90.00. The answer is 90.
Question: Aisha enjoys listening to music on her mp3 player. She starts with 500 songs on her mp3 player, then adds another 500 the week after that. She realizes her mp3 player has a large capacity for storing songs so she adds twice the amount she already had on her mp3 player. After a while, though, she decides that she doesn't like 50 of the songs and removes them. How many songs are on Aisha's mp3 player now?
Answer:
Aisha starts with 500 songs + 500 songs = 1000 songs added to her mp3 player in the first two weeks. After that Aisha adds twice that amount to her mp3 player, 1000 x 2 = 2000 songs added. She now has 1000 + 2000 = 3000 songs on her mp3 player. However, she decides she wants to remove 50 of them, 3000 - 50 = 2950 songs on her mp3 player. The answer is 2950.
