Question

Suppose a city with population 600,000 has been growing at a rate of 4​% per year. If this rate​ continues, find the population of this city in 25 years.

Answer 1

15,600,000

Explanation:

We start with our initial population of 600,000. Then multiply that with the rate of 4% (0.04 in decimal, or 1.04 so that the 0.04 is automatically added to the 600,000.)

• 600,000 · 1.04y = projected population
• y = 25
• 600,000 · 1.04(25) = projected population
• simplify!
• 15,600,000 = proejcted population
