Answer:

y=370,000(1.091)^t

Step-by-step explanation:

The formula for exponential growth is;

y=a(1+r)^x

where

y=future growth

a= initial population

r=growth rate as a decimal

x=number of time interval that have passed

Given;

a=370,000

r=9.1% =0.091

x=t

Thus

y=370,000(1+0.091)^t

y=370,000(1.091)^t
