Reasoning & answer: CoT: First find how many giraffe statues Nancy can make by dividing the total amount of jade by the amount used per giraffe statue: 1920 g / 120 g / giraffe = 16 giraffes. Then multiply that number by the price per giraffe to find how much Nancy earns total from giraffes: 16 giraffes * $150 / giraffe = $2400. Then find how much jade each elephant statue uses by doubling the jade used by the giraffe statues: 120 g / giraffe * 2 = 240 g / elephant. Then find how many elephant statues Nancy can make by dividing the total amount of jade by the amount used per elephant statue: 1920 g / 240 g / elephant = 8 elephant. Multiply that number by the price per elephant to find Nancy's total earnings from elephants: 8 elephants * $350 / elephant = $2800. Finally, subtract Nancy's total earnings from the giraffes from her total earnings from the elephants to find the difference: $2800 - $2400 = $400.
The answer: 400
Question: Nancy carves statues out of jade. A giraffe statue takes 120 grams of jade and sells for $150. An elephant statue takes twice as much jade and sells for $350. If Nancy has 1920 grams of jade, how much more money will she make turning it all into elephants instead of giraffes?

Reasoning & answer: CoT: Ivy has 60 / 2 = 30 dolls. Ivy has 30 / 3 * 2 = 20 collectors edition dolls.
The answer: 20
Question: Dina has 60 dolls. She has twice as many dolls as Ivy. 2/3 of Ivy's dolls are collectors editions. How many collectors edition dolls does Ivy have?

Reasoning & answer: CoT: First find the amount of dye each blouse takes: 20 dots / blouse * 10 ml / dot = 200 ml / blouse. Then multiply the dye used per blouse by the number of blouses to find the total amount of dye used: 200 ml / blouse * 100 blouses = 20000 ml. Then divide the amount of dye needed by the amount of dye per bottle to find the number of bottles needed: 20000 ml / 400 ml / bottle = 50 bottles.
The answer: 50
Question: Jenna is adding black dots to a bunch of white blouses. Each blouse gets 20 dots, and each dot takes 10 ml of black dye. How many 400-ml bottles of dye does Jenna need to buy to dye 100 blouses?

Reasoning & answer: CoT: The Saturday morning exodus out of the park comprised 4 * 2880 = 11520 elephants. This means that after the exodus, the park was left with 30000 - 11520 = 18480 elephants. Since the final number of elephants was 28,980, the new elephants that entered were 28980 - 18480 = 10500. The rate at which the new elephants entered the park was therefore 10500 / 7 = 1500 elephants / hour.
The answer: 1500
Question:
Utopia National Park hosted 30,000 elephants on Friday night. The next morning, there was a 4-hour elephant exodus out of the park, at a constant rate of 2,880 elephants/hour. Over the next 7-hour period, new elephants entered the park at a constant rate. If the final number of elephants in the park was 28,980, at what rate did the new elephants enter the park?
