Expert Solution

2 = e^24r

ln2 = 24r

r = ln2/24 = about .029

 

A = 356,000e^.029t

A = 356,000e^.029(96)

A = 356,000e^2.7726

A = 356,000(16)

A= 5,696,000 in 96 years

in 24 years the population = 2(356,000) = 712,000

in another 24 years = 48 years, the population = 2(712,000) = 1,424,000

in another 24 yers = 72 years, the population = 2(1424000) = 2,848,000

 

in another 24 years = 96 years the population = 2(2848000) = 5,696,000
