The exponential model A=64.5e^0.02t describes the population, A of a country in millions, t years after 2003. The population of the country will be 108 million in

we have the expression

A=64.5e^0.02t

For A=108

substitute

108=64.5e^0.02t

108/64.5=e^0.02t

Apply ln both sides

ln(108/64.5)=ln(e^0.02t)

ln(108/64.5)=0.02t(ln(e))

ln(108/64.5)=0.02t

solve for t

t=ln(108/64.5)/0.02

t=26 years

therefore

2003+26=2029

answer is

year 2029
