1 What is the growth factor if water usage is increasing by

1. What is the growth factor if water usage is increasing by 8% per year. Assume that time is measured in years.

2. What is the growth/decay factor per decade for a city whose population grows by 25% per decade?

The growth/decay factor is b=

(1)

Since the water usage is increasing by 8% per year, therefore its growth factor is given by

growth factor=(8/100)^t (where \"t\" is in year)

therfore

growth factor =(0.08)^t

(2)

Since the population of the city is increasing by the 25% per decade, therefore growth facor is given by

growth of the population (b)=(25/100)^t (where t is in decade)

growth factor (b)= (0.25)^t
