Answer the following question.
Peter is buying a set of glasses. They cost $3 for small glasses and $5 for large ones. He has $50. If he buys 8 small ones and leaves with $1 in change, how many large ones did he buy?
Step-by-step reasoning process: He spent $49 on glasses because 50 - 49 = 1. He spent $24 on small glasses because 8x3 = 24. He spent $25 on large glasses because 49 - 24 = 25. He bought 5 large glasses because 25 / 5 = 5.
The answer is 5.

Sara sent letters to her friend in China every month. She sent 6 letters in January, 9 letters in February, and in March she sent triple the number of letters she sent in January. How many letters does Sara send?
Step-by-step reasoning process: Combining January and February, Sara sent 6 + 9 = 15 letters. In March, she sent 3 * 6 = 18 letters. Altogether, Sara sent 15 + 18 = 33 letters.
The answer is 33.

Answer the following question.
Patrick has 4 hours less than twice the amount of time that Greg has left to finish his homework. Greg has six hours less than Jacob left to finish his homework. If Jacob has 18 hours left to finish his homework, calculate the total number of hours they all have left to finish their homework?
Step-by-step reasoning process: If Jacob has 18 hours left to finish his homework, Greg has 18 - 6 = 12 hours left to finish his homework. The total number of hours Jacob and Greg have left to finish their homework is 12 + 18 = 30 hours. Patrick has 4 hours less than twice Greg has left to finish his homework, meaning Patrick has 4 hours less than 12 * 2 = 24 hours left to finish his homework. Patrick has 24 - 4 = 20 hours left to finish his homework. Altogether, the three have 30 + 20 = 50 hours left to finish their homework.
The answer is 50.

Answer the following question.
Carolyn is planning out her final essay. The introduction will be 450 words, the conclusion will be triple the length of the introduction, and each of the four body sections will be the same length. If her essay has to be 5000 words total, how long is each section?
Step-by-step reasoning process: First find the length of the conclusion by tripling the length of the introduction: 450 words * 3 = 1350 words. Then subtract the length of the introduction and conclusion from the total length to find the combined length of the body sections: 5000 words - 1350 words - 450 words = 3200 words. Then divide the combined length of the body section by the number of body sections to find the length of each section: 3200 words / 4 sections = 800 words / section.
The answer is 800.
