Reasoning & answer: CoT: Betsy jumps half as long as Cindy, who jumps for 12 minutes so Betsy jumps 12 / 2 = 6 minutes. Tina jumps three times as long as Betsy, who jumps for 6 minutes so Tina jumps 3 * 6 = 18 minutes. Tina can jump for 18 minutes and Cindy and jump for 12 minutes so Tina can jump 18 - 12 = 6 minutes longer.
The answer: 6

Reasoning & answer: CoT: Let x represent the number of Khaki Campbell ducks. Cayugas:3 + 2x. Muscovies:4 + (3 + 2x) = 7 + 2x. Total: x + 3 + 2x + 7 + 2x = 90. 5x + 10 = 90. 5x = 80. x = 16. Muscovy: 7 + 2(16) = 39.
The answer: 39
Question: There are 4 more Muscovy ducks than Cayugas, and 3 more than twice as many Cayugas as Khaki Campbells. If there are 90 ducks total, how many Muscovies are there?

Reasoning & answer: CoT: If the art piece was bought at $4000, and its price in three years will be three times its buying price, it will be worth 3 * $4000 = $12000 in another three years. The price of the art piece will increase by $12000 - $4000 = $8000.
The answer: 8000
Question: Three years ago, Rosie purchased an art piece for $4000. The same art piece will be three times as much in another three years. How much money will the art piece have increased by?

Reasoning & answer: CoT: Conor can chop 12 x 4 = 48 eggplants a week. He can chop 9 x 4 = 36 carrots a week. He can chop 8 x 4 = 32 potatoes a week. Therefore, Conor can chop 48 + 36 + 32 = 116 vegetables a week.
