The formula for population growth is written as [tex] f(t) = a(b)^t [/tex] , where t is the growth factor.
And the formula for growth factor is b = 1+r , where r is the rate of increase
So for our question
b = 1.15
that implies
1+r = 1.15
subtract 1 from both sides
So , r= 0.15
So to change in percent , multiply by 100
we get
r= 15%
rate of increase = 15%
Answer:
the rate of increase is 15%
