According to the world population....?

Question

According to the US Census, the world population Upper P, in billions, was approximately

Upper P=6.7 e^0.011 t

where t is in years since January 1, 2007. At what rate was the world’s population increasing on that date?

Give your answer in millions of people per year. 

 

I got 6700 million people/year but it says the question is wrong. Please help

Answer 1

P = P₀·(1 + rate)^t

 

e^0.011 = 1 + rate

e^0.011 - 1 = rate

0.011 = 1.1% = rate = 74,106,840 people per year in 2007
