Complete the following table Population growth rate k Doubli

Solution

Country A : P = Poe^(r*t)

r = 1.7%; t = doubling time

2Po = Poe^(0.017t)

2 = e^(0.017t)

Take natural log on both sides:

ln(2) = 0.017t

t = 40.77 years

Country B:

find growth rate: P = Poe^(r*t)

2Po =Poe^(46k)

2 = e^46k

take natural log on both sides:

ln2 = 46k

k =0.015

k = 1.5%
