The annual rate of increase of a population is equal to 2% of the size of the population. y y\,y is the population in millions and t t\,t is the time in years.
Write down a differential equation for this relationship
Show that y=Ae0.02ty = Ae^{0.02t}y=Ae0.02t where A A\,A is a constant
Given that the initial population is 2.5 million. Find the population after 10 years.
