## teller one year ago Can someone please help me on this ? A city has a population of 350,000 people. Suppose that each year the population grows by 5.5%. What will the population be after 10 years?Use the calculator provided and round your answer to the nearest whole number.

1. teller

How do I round it off ? would it just be 350?

2. teller

I'm confused..

3. anonymous

1.1 divided by 2 = ?

4. teller

0.55

5. teller

192500?

6. teller

times it by 10?

7. teller

542500?

8. teller

so it would be 543?

9. teller

so just 542500?

10. campbell_st

use $Population = 350000\times(1 + 0.055)^{10}$

11. teller

it said it was wrong..

12. campbell_st

this is an application of exponential growth... and uses the compound interest formula as shown above
