the country of Benin in West Africa has a poluation of 12.12 million people. the population is growing at a rate of 3.1% each year. What function can be used to find the population 7 years from now?

Answer 1

P(t) = 12.12(1 + 0.031)^t

P(7) = 12.12(1.031)⁷

Answer 2

This is an example of exponential growth. The growth law for this problem is

p(t) = (12.12 x 10⁶) (1.031)^t,

where t is the number of years elapsed. Plug t=7 into p(t) and evaluate.
