Answer:

117417 people

Step-by-step explanation:

Let's use the equation A = Pe^rt.

A = amount

P = starting amount

r = rate

t = time

Let's find r first using years 2002 and 2003.

35200 = 32000e^r

Divide each side by 32000.

35200/32000 = e^r

Take the ln() of each side.

r = ln(35200/32000)

Now we can solve for year 2015.

A = 32000e^ln(35200/32000)*13

A = 32000e^1.2390323374562242

A = 110473
