The U.S. population in 1990 was approximately 250 million, and the average growth rate for the past 30 years gives a doubling time of 66 years. The above formula for the
United States then becomes
P (in millions) = 250 times 2( y1990)/66
What will the population of the United States be in 2025 if this
growth rate continues?
Did I do this correct
P=250*2^(20251990)/66
p=250*2^35/66
p=250*2^.53
p=250*1.444
p=361 million
is this correct if not please explain what i did wrong
i don't think that it is (2^),isn't it suppose to be times by two?
so,
P=250*(2*(20251990)/66)
P=250*(2*(35/66))
P=250*1.06
P=?
and you have your final answer here! =)
carry, you are right.
