Question

a country's population in 1990 was 1554 million. in 2001 it was 159 million. estimate the population in 2005 using the exponential growth formula

Answer 1

P = P0 e^kt
P = 159,000 , P0 = 154,000 and t = 2001 - 1990 = 11
plug these values into the formula and find the value of k

Answer 2

then you can use the formula to do the estimate
