The population of a town is growing according to the differential equation
dy/dt =ky
The growth constant, k, is equal to 0.11 year -1.
The size of the population at the start of the year 2000 was 30 thousand.
Since the population is growing exponentially, the population in year t is given by
y=30e^0.11t
Here, y is measured in thousands and t is measured in years since 2000.
