If the population of a city grows 25% in 3 years, what is the yearly growth rate?
Population Growth Rate:
In mathematics, populations can be modeled as growing at various rates. This applies to populations of cities, countries, or other sizes of community.
Answer and Explanation:
8%. The population grows at 8% per year, resulting in the population x (1.08)^3 = 1.25 times as many people, or 25% growth, in three years. A higher annual growth rate would yield too high an amount over three years and vice versa for smaller growth rates.
