What is exponential growth?

An exponential growth problem is one for which we define the model; P= Poe^rt

Where;

P = population at time t

Po = initial population

r = population growth rate

t = time taken

1800000 = 900,000e^(0.012 × t)

1800000/900,000 = e^(0.012 × t)

2 = e^(0.012 × t)

ln2 = 0.012 × t

t = ln2/0.012

t = 58 years
