Answer: A = 72000(1.034)^8

Explanation:

Hi, to answer this question we have to apply an exponential growth function:

A = P (1 + r) t

Where:

p = initial population

r = growing rate (decimal form)

t= years

A = population after t years

Replacing with the values given:

A = 72000 (1+ 3.4/100) ^8

A = 72000(1.034)^8
