Question

A country's population in 1991 was 147 million. In 1998 it was 153 million. Estimate the population in 2017 using the exponential growth formula. Round your answer to the nearest million.

P=Ae^kt

Answer 1

k = ln (153/147)/7
k = ln ( 1.0408163265)/7
k = 0.040005334584

y(t) = a * e ^ k*t

y(2017) = 147 * e^ 0.040005334584 * 26
y(2017) = 147*e^ 1.0401386992
y(2017) = 147* 2.8296094512
y(2017) = 415.95 NOT very sure of that answer

Answer 2
