A country's population in 1995 was 228 million. In 2001 it was 230 million. Estimate the population in 2010 using the exponential growth formula. Round your answer to the nearest million

Question

dumbcow · Answer

$$P _{t}=P _{0}e ^{kt}$$
Find k
$$230 = 228*e ^{6k}$$
$$k = \frac{\ln 230/228}{6}$$
Substitute this value in to find P15
2010-1995 = 15
$$P _{15}=228*e ^{15*\ln (230/228)/6}$$
