Answer:

2150 people

Explanation:

You want the number of people in a town after 10 years if the initial population of 1600 is growing at 3% per year.

Exponential growth

Exponential growth can be modeled by the equation ...

p(t) = a·b^t

where a = p(0) = the initial population, and

b = annual growth factor = (1 + annual growth rate)

Application

The problem statement tells you p(0) = 1600, and the growth rate is 3%. This means the equation modeling the population is ...

p(t) = 1600·1.03^t

Ten years

The population in 10 years is modeled as ...

p(10) = 1600·1.03^10 ≈ 2150

The population of the town after 10 years is expected to be about 2150 people.

The population of a small town is 1600 and is growing exponentially at a rate of 3% per-example-1
