Question: Lauryn owns a computer company that employs men and women in different positions in the company. How many men does he employ if there are 20 fewer men than women and 180 people working for Lauryn?
Answer: Step-by-step reasoning process: Let's say the number of men working at the company is x. Since there are 180 people, and the number of men is 20 fewer than the number of women, then x + x + 20 = 180. The total number of employees in the company is 2x + 20 = 180. 2x = 180 - 20. 2x = 160. The number of men is x = 160 / 2. There are x = 80 men in the company.
So the answer is 80.

Question: A library cabinet houses five ancient scrolls. The first scroll is 4080 years old. If each scroll is older than the last by half as many years as the last scroll's age, how old is the fifth scroll?
Answer:
Step-by-step reasoning process: The second scroll is 4080 + 4080 / 2 = 4000 + 2040 = 6120 years old. The third scroll is 6120 + 6120 / 2 = 6120 + 3060 = 9180 years old. The fourth scroll is 9180 + 9180 / 2 = 9180 + 4590 = 13770 years old. The fifth scroll is 13770 + 13770 / 2 = 13770 + 6885 = 20655 years old.
So the answer is 20655.
