Question: James wants to learn to become a chess grandmaster. It takes 2 hours to learn the rules. It then takes him 49 times that long to get a level of proficiency to start playing in local tournaments. After that, he devotes his life to chess and spends 100 times as much as the combined time to get proficient to becoming a master. How much total time did he spend?
Answer with step-by-step thinking: It takes him 2 * 49 = 98 hours to go from knowing how to play to proficient. So he spends 98 + 2 = 100 hours combined on those. So it takes him 100 * 100 = 10,000 hours to become a master from proficient. So the total time was 100 + 10000 = 10,100 hours.
So the answer is 10100.


Question: Shelby had $20 to take to the book fair. She bought one book for $8 and another for $4. She decided to buy as many $4 posters as she could with the money she had left. How many posters can she buy?
Answer with step-by-step thinking: She spent $8 + $4 = $12 on books. She started with $20, so she has $20 - $12 = $8 left to spend on posters. Each poster costs $4, so she can buy $8 / $4 = 2 posters.
So the answer is 2.


Question: One white rhino weighs 5100 pounds and one black rhino weighs 1 ton. How many pounds would 7 white rhinos and 8 black rhinos weigh in total?
Answer with step-by-step thinking:
5100 * 7 = 35,700 pounds. 1 ton = 2000 pounds. 8 * 2000 = 16000 pounds. 35,700 + 16,000 = 51,700. Seven white rhinos and 8 black rhinos would weigh 51,700 pounds.
So the answer is 51700.
