A country population in 1991 was 231 million in 1999 it was 233 million. Estimate the population in 2003 using the exponential growth formula. Round you answer to the nearest million

P (y) = ir^t

233=231r^ (1999-1991)

(233/231) ^ (1/8) = r

p (y) = 231 (233/231) ^ ((y-1991) / 8) so in 2003

p (2003) = 231 (233/231) ^ ((2003-1991) / 8)

p (2003) = 231 (233/231) ^ (1.5)

p (2003) = 234

So 234 million (to the nearest million people)
