Given that the population of a town today is 33,000 people.
If the population decreases with a constant rate of change and the decrease is 7% in the first year.
The decrease in the population of the town in the first year is given by 0.07 x 33,000 = 2,310
The decrease in the population of the town in 6 years is given by 2,310 x 6 = 13,860
Therefore, in 6 years, the town's population will be 33,000 - 13,860 = 19,140
