Acountry's population in 1990 was 48 million. in 1997 it was 51 million. estimate the population in 2017 using the exponential growth formula. round your answer to the nearest million.

Hi there
First find the growth rate between 1990 and 1997
The formula is
P=Ae^rt
P 51 million
A 48 million
E constant
R growth rate?
T time 1,997−1,990=7 years
We need to solve for r
R=[log (p/A)÷log (e)]÷t
R=(log(51÷48)÷log(e))÷7
R=0.009

Now find the population in 2017
P=Ae^rt
P ?
A 48 million
R 0.009
T time 2,017−1,990=27 years
So
P=48×e^(0.009×27)
P=61 million

Hope it helps
