Hi, I am taking a course "math for elementary teachers" and I have two problems. - How thick is a sheet of paper in your textbook.
- A little island has a population of 1,000 people. It doubles every 30 years. What will the population be in 30 years?, in 60 years?, when will it be over one million?
Hi DJ,
- How thick is your book? (just the pages not the cover)
How many pages does it have? So, how thick is each page?
- If the population doubles every 30 years then there will be 2,000 people after 30 years. The population will double again in the next 30 years. Keep doubling until you get more than 1,000,000.
