growth and factor per decade

Question

What is the growth/decay factor per decade for a city whose population grows by 24% per decade?

Answer 1

Growth factor = 1.24

Exponential Growth Formula:

Y = A • (1+R)^X

Where:

A is the initial population

X is the number of decades

R is the growth rate

(1+R) is the growth factor

The growth rate is 24% or .24∴

∴ the growth factor is (1+R) = (1+ .24) = 1.24

Growth factor = 1.24
