Reasoning & answer: CoT: He spent 17 + 11 = 28. So, he still has 100 28 = 72 remaining.
The answer: 72
Question: John goes to the market with 100. He buys a roast for 17 and vegetables for 11. How much money does he have left?

Reasoning & answer: CoT: If "x" is the number of European swallows, then, for every one European swallow, there would be 2x American swallows. Thus, the total number of swallows would be 2x + x = 90 swallows. Thus, the number of European swallows x = 30. And the number of American swallows is 90 - 30 = 60. A European swallow can carry twice what an American swallow can carry, or 2 * 5 = 10 pounds. 30 European swallows can carry a maximum of 30 * 10 = 300 pounds. 60 American swallows can carry a maximum of 60 * 5 = 300 pounds. Thus, a flock of 90 birds, with 30 European and 60 American swallows, can carry 300 + 300 = 600 pounds.
The answer: 600
Question: The American swallow can lift into the air and carry a maximum of 5 pounds of weight, while the European swallow can lift and carry twice the weight as the American swallow. If there was a flock of 90 swallows, containing twice as many American as European swallows, what is the maximum combined weight the flock can carry?

Reasoning & answer: CoT: If Marvin solved 40 math problems yesterday, he has solved 40 * 3 = 120 math problems today. The total number of math problems that Marvin has practiced is 120 + 40 = 160. Arvin has practiced twice as many as Marvin, so has practiced 160 * 2 = 320 problems. Together, Marvin and Arvin have solved 320 + 160 = 480 math problems.
The answer: 480
Question: The number of math problems that Marvin practiced today is three times as many as the number of problems he solved yesterday. His friend, Arvin, has practiced twice as many math problems on each day. How many math problems have they practiced altogether if Marvin solved 40 math problems yesterday?

Reasoning & answer: CoT: Micah drank 1.5 x 3 = 4.5 liters in the afternoon. She drank a total of 1.5 + 4.5 = 6 liters of water.
The answer: 6
Question:
