Question

Suppose the population of a town is 8,200 and is growing 3% each year. Write an equation to model the population growth. Predict the population after 3 years

Answer 1

P=8200(1.03)t P is the population after t years. t=3 P=8200(1.03)3=8960.3614=8960

Answer 2

x = population after 3 years

y = starting population

r = percentage

n = number of years

x = y *(1+r)^n

x = 8200 * (1 +0.03)^3

x = 8960.36

so about 8960 people in 3 years
