Question

A city has a population of 320,000 people. Suppose that each year the population grows by 3.5%. What will the population be after 13 years?

Answer 1

500,466

Explanation:

Each year the population is multiplied by 1.035, so after 13 years, it will be multiplied by that factor 13 times, or 1.035^13.

320,000 · 1.035^13 = 500,566
